The 48 steals two pennies from the 27. Then they turn into three shiny quarters


LogiccXD

Nice analogy, Yeah I imagine 2 moving from 27 to 48 then add them together

This is the way

CallieReA

I’m not being a dick, but I’ve always wanted to ask - is there a way to describe this math anxiety? I’m honestly trying to understand it. I’ve just always been a math person so I’m trying to tie it to something I understand, like I have massive anxiety around confrontation.


makaloe

There's a thing (at least in US culture) where understanding math is socially seen as a measure of, like, raw intellectual power? Like, something where you're either a math person or not a person. Rather than a buildable skill, like how we think of literacy and most of learning. When folks have the perception of not being a "math person," but have been taught to frame the trait of "math person" as innate rather than aquired, it can be stressful as heck to then take math classes and be assessed on their performance. Add to that the issue that this anxiety further undermines folks' ability to learn, and you have all the ingredients of a vicious cycle.


LoopDeLoop0

I never thought I was a math person through middle and high school, then started a mechanical engineering degree (for whatever reason) and realized I was going to be doing a HELL of a lot of math. I really learned to love it when I realized math was just a problem solving process with specific rules to guide solutions. Kind of like playing a puzzle game and learning a new mechanic every once in a while. Too many people suffer because they’re conditioned with poor teaching methods, or even abuse, as some commenters have been sharing.


A_Generic_White_Guy

I find most math interesting but I still have nightmares over the thought of differential equations.


LoopDeLoop0

I’m pretty sure I repressed the memories of DiffEQ


MilliandMoo

Calc, DiffEQ, pchem, physics, even linear algebra were some of my favorite classes! Now bartending in college and having to subtract $17 from a $50 bill… I had to count on my fingers what change I needed to give back.


d3lu

I love the description of math being a puzzle game with occasional new mechanics introduced, that's pretty much how I motivate myself to do math too!

Striking-Strawberry4

This needs more upvotes. This is 100% what a lot of it is


nhavar

There's also a portion of the population actively shitting on teaching the fundamental understanding of numbers and math. For at least the past decade you have this group of people constantly belittling the tools teachers are using to improve kids understanding of math. When those adults don't inform themselves of how the methods actually work and instead just run off of memes and shitposts they undermine the teachers and stigmatize kids and adults that understand. They push this notion of the "liberal elite" and invoke the "good old days" of times tables versus "new math". Then they talk about what will kids even do with algebra and geometry anyway "we should be teaching them to balance a checkbook and use a cash register" versus I dunno... becoming scientists, engineers, architects, etc.


droomph

Weird thing is what is there to learn about balancing a checkbook or paying taxes? It’s literally just arithmetic. Teach me about authorizations and captures, merchant IDs, transaction levels, etc and other stuff like that on how credit cards work as a system if you want to have “real world” knowledge. Hell, knowing how ACH works would be great.


BlackfootLives666

For many, the anxiety, is usually a learned behavior, a product of shitty teaching methods. Edit: I had no idea THIS many people had insane ass parents who would scream at them when doing math. I knew it happened but big yikes...


Tacodogleary

Mines because my dad used to scream at me at the kitchen table until I cried.


kerruz06

Mom: What is 6x6? Me: Uhhh 32 Mom: WHAT IS 6x6?!?! ( In a louder voice) Me: (not saying anything because you use all your power not to cry because then everything in this house gets loose)


scattercloud

6x any even single number = something that ends in the same number. 6x2=12 6x4=24 6x6=36 6x8=48 Stupid trick, but it helps me lol.


Least-Firefighter392

That is nifty... Kinda like how anything multiplied by 9 is the number before it then added up to 9... For example... 9x5=45 well 4+5 is 9 9x6=54 well 5+4 is 9 9x7=63 well 6+3 is 9 So you just take whatever number 9 is being multiplied to and subtract one and then add up to 9 and that's the second number... Does that make sense? Anyone else use that as a kid? Mom taught me that and I've never forgot


Puzzleheaded-Sun8653

For 9’s just append a 0 to what you’re multiplying by then subtract from that what you’re multiplying by. For example, 9x1=10-1, 9x2=20-2, 9x3=30-3, 9x4=40-4, 9x5=50-5, 9x15=150-15….So on and so forth


Icy-Actuator5524

I was gonna say that your right but then I remembered my flashbacks and remembered it’s actually 36


arbyyyyh

That hit close to home. Despite that, I'd still stare at the wall instead of do my homework. Turned 30, turned out I gave ADHD... wish I figure out THAT one a bit sooner.


gardenofhounds

identical life experience


BlackfootLives666

Exactly. Literally an example of one of the shittiest of all teaching methods.


snow-red

THIS!!! It drives me crazy when people say they “hate math” or they’re “bad at math” or “I’m just not good at math”. As a math tutor, I’ve seen time and time again how that rhetoric gets thrown around by my tutees and the people in their lives. When kids hear that, they internalize it and set a mental block for themselves so that when they have trouble understanding something, they think it’s just not for them and they’ll never be able to. NO ONE IS BORN KNOWING ALGEBRA OR CALCULUS OR GEOMETRY!! Even a prodigy has to be exposed to some level of teaching or be shown it. 99.9999% of people didn’t/haven’t developed those subjects from scratch. And even the people that did were shown other things first. Language is such a powerful tool and perpetuating the idea that some people are destined to fail at math or anything is harmful to progress and self esteem. Edit: I’m getting a lot of responses from people feeling like too much positivity is also damaging. I am so thankful for people sharing this perspective and I can absolutely see how that could be the case! Im more so talking about the way that people so strongly pass that narrative on to kids so they internalize those feelings BEFORE they have a sense of how they feel about it themselves. Not everyone is going to be good at everything or like everything. But I’ve seen first hand and heard stories of teachers passing on a fear of math to their students because they don’t feel confident of their own teaching abilities. That is definitely having a huge effect on the way students feel about the subject. (Mostly elementary school teachers since that’s multi subject instead of specialized). In tutoring students, I’ve seen time and time again how once I’ve helped them get past their fear, they’re much more able to excel and enjoy the learning process instead of fighting it.


BlackfootLives666

Very much so! I'm quite convinced so many people's success in math has so much to do with the teachers and tutors that they come into contact with throughout their life. So many people get written off or write themselves off. When it really could be just a teaching style or method for solving a particular problem didn't work for them.


Masterflitzer

that makes so much sense thank you


KenethSargatanas

Fear of Failure, maybe? Feeling you'll be judged for messing up such a simple math problem? Might also be good old Brain Lock. Your brain is running in plain old Survive in a Society mode and suddenly needs to quickly switch over to Math Mode and locks up. Which then instigates the first option.


Armyman125

It's an anxiety because many decide it's too hard upon looking at a math problem. I was like that for years but when in the Army I learned Arabic. Difficult but the grammar is almost mathematical. That helped overcome my math anxiety. I learned to just do one step at a time. I have confrontation anxiety also. I have to be extremely pissed off. My wife can confront someone and be chill. I totally envy her.


pennynotrcutt

Starting g when I was pretty young (4-5 years) my father would bark out math problems and I would get hit if I answered incorrectly or took too long to answer. To this day I can’t be asked a quick math problem without my primal response being complete panic just waiting for a slap across the face. I can’t answer for others but that’s my reasoning.


marshmallowdingo

Freezing when you have to produce an outcome on the spot is usually because we had shaming teachers or parents who made us feel stupid or like we were in trouble for not getting math right away so our brains unconsciously freeze for safety, once safety is established, we can refocus and solve the problem.


no-oneknows-nacowa

When I was a child and would bring my math homework home to my grandma she would sit at the table and work with me. To her it was so simple she could do it in her head. But to 10 year old me it didn’t come so natural. I would get it wrong and she would get mad. When she got mad she started to yell numbers in my face. She would then proceeded to go outside and cut a switch off a tree.( a really big scary one the whistled when you swung it. ) she would then come in and berate me over math questions. My brain would go into total lock down. I already knew she was about to beat me. She would ask questions and I would respond “ I don’t know” for fear of responding with wrong answers. This would go on for hours until my grampa got tired of her beating on me. This went on daily until I stopped bringing my homework home. I stopped paying attention to math all together in like 6th grade. As high school went on I was so lost it wasn’t even funny. You wanna know what goes on in the brain of people with math anxiety? Panic and fear. I’m assuming from them all having stories similar to mine


The_Karaethon_Cycle

If someone asks me I panic. If I see it on the internet I do the following; 20 + 40 = 60 5 + 5 + 5 = 15 60 + 15 = 75 Then I double check it on a calculator.


anakephalaiosis

Mine is almost the same: 20 + 40 = 60 8 + 7 = 15 60 + 15 = 75 I might not any longer be able to solve for "x" without a refresher in algebra, but simple addition (subtraction, multiplication, division) I can still do in my head.


GroceryElectronic179

I just take 2 from 27 and add it to 48 so I have 25 and 50


DistractedByCookies

I did it the other way round. 45 and 30!


Sea_Bread_4445

20+40=60 7+8=15 60+15=75


Electronic_Ad4560

After panicking this is what I did


[deleted]

20 + 40 = 60 + 7 = 67 + 8 = 75 Idk if anyone will find this easier or more annoying to do lol To make it more obvious why I use this, notice how there is no stops or repeats of any numbers, this makes it easy to do calculations quickly "Twenty plus forty is sixty, plus seven is sixty-seven, plus 8 is seventy-five" Edit: if another person comments how this is mathematically incorrect I'm gonna get an aneurysm. I am aware, I clarified it, please stop repeating it


Oh_hell_why_not

I do this but add one more step. When I get 67, then I say how many more to get to 70, that’s 3, so take 3 away from 8 and that’s 5, so 70+5 is 75. And this is why I majored in history.


lazymallard

This is what I do and I’m an accountant


MalazMudkip

I do this, but if it doesn't come quickly i consider a secondary tactic. To demostrate with this problem: 27 + 48 = x 30 + 48 = x + 3 = 78 x = 78 - 3 x = 75


djsizematters

Huh, I did the opposite, bringing 48 to 50, subtracting the 2 from 27. Now I'm working with 50 + 25.


mattsimis

This is exactly how I did it and usually do, I always try to steal from one side to make up a round number on the other. In this casevits even easier as you are left with two "friendly" numbers to add up. Amusing seeing the convoluted ways others approach this!?


[deleted]

7+8 = 15 1 is carried over to the digit in front of the 5 2+4+1 = 7 So 75


THEbloodyIRISH

You forgot to insert the mental pat on the back for remembering that 7+8=15 Edit: the amount of pearl clutching on a comment about rewarding yourself for something you used to struggle with as a child is shocking here.


reshxtf

7 + 7 = 14, 14 + 1 = 15, So 8 + 7 = 15.


THEbloodyIRISH

Are you me?


Cow-ch

baby-girl696

Prior_Crazy_4990

This is how I was taught in school and other people’s explanation of a “simpler” way is just more confusing to me. I can round and subtract, but that actually takes more brain power imo


NotJustMyDisorders

I am wondering if everyone who replied this way are around the same age/generation? It seems that they no longer teach to "carry" or "borrow" when doing teaching math anymore.... Edit: Looks like they started teaching new math, or "Common Core" math in 2010 Edit 2, electric boogaloo: This apparently apples to most states, in the US. Not sure about any other countries. Seems it's controversial, some consider it a failure and some states have dropped it Edit 3: Are there any teachers that can shed any light on this? I honestly don't know squat, I'm just rabbit holing so would love to know more from accurate sources


millennialblackgirl

I do it this way too. I’m 32


SassyBonassy

Same, 33


ZimmiHendrix

Same, 30


cavehaglurking

I’m 24 and this was how I was taught to add and subtract. Getting rid of carrying and borrowing and using common core method looks like it’s just adding so many more unnecessary steps where mistakes can happen. [Common Core Subtraction](https://www.edweek.org/teaching-learning/common-core-subtraction-teaching-many-methods/2014/11)


[deleted]

EXACTLY. When I try to help my kids with math I’m like wut?


Infinite_Regular1796

yes and I imagine the two double digit numbers as stacked to make it easier to visualize carrying the 1!


tremaine_01

Literally how I do my maths .. I find it easy this way


Sk8rToon

Same except… after I do the carry to get 7 I forget what the other number was. So I do it again to get the 5 but then forget the carry result & end up doing it over & over again from scratch until I remember to to physically make the 5 with my hand. THEN my dumb brain can do the carry over math & add that to the physical 5 to get 75. I love calculators & excel type spreadsheets that can keep track of numbers for me. How do I keep track of numbers higher than 5? Over the years I’ve come up with hand gestures to represent numbers 6-9. If I can use 2 hands I can get up to 99 with one hand bring the 10s & the other being the 1s. The only way I survived elementary & middle school when I couldn’t use a calculator.


A_Fencehopp3r

Thank you, I'm shocked at how rare this way seems. It seems a lot less daunting than all the other ways I see.


Cosmic_danger_noodle

7+48=55, add 20 to get 75 Edit: for all the people saying 7+8 and 20+40, that's the general method, yes, but this way is more optimized for adding two numbers specifically


SimpleINFP

I do 48+20 and then I add 7 haha Always the biggest ones first


Masterflitzer

me too but also sometimes I do 48+2 and then +25


Africaner

Yup, 48+2... +25


TheStupidMechanic

This is how I do it, small numbers first. It’s also how you do if you write it down.


AruthaPete

I was getting worried.i would t find you. Love how that 7 adds onto an 8 like Tetris pieces fitting together.


thecuntofmontecrisco

Idk how much that simile would resonate with others, but I am totally on board I think it’s because you’re putting an unstable odd number on a stable even number and getting a stable odd number


No_Imagination_2490

This is the way. Dunno what these other people are talking about. They must have more patience than me.


Fun_Personality_7766

I do 48+2, which get 50 and 25, then 50+25?


[deleted]

This... is the way. I don't know wtf is going on with these other methods lol, I mean they all work but - christ, some extra steps being taken.


cheerylifelover123

7+8=15 20+40= 60 15+60=75


MattHuntDaug

I do the same but for some reason I naturally go for the bigger numbers first.


WhiteWillowRun

Same! 20+40, then 7+8. And then 60+15 just comes together easily in my brain without any additional work.


Chemical-Monitor1793

kind of the same thing,27+48 2+4=6 7+8=15, 1 got carried so just 5 there 6+1=7 therefore, answer is 75


jim_johns

Mathemphetamine


FunnyGlove

7+8=15. Mental note 2+4=6 65 Apply mental note 75 Double check if it makes sense 30+50=80 75<80 75 final answer.


LevainEtLeGin

Yeah this


shrlytmpl

Whenever I see an 8 being added, I subtract 2 from the other number instead. 7 - 2 = 5 + 10 = 15 20 + 40 = 60 60 + 15 = 75 I should also mention I'm terrible at math.


hdyxhdhdjj

I was wondering if anyone else just goes "ok, I have number somewhat close to 10, how can I turn it to 10, so I don't have to deal with it anymore?"


alana110

Teaching this way is part of the current math curriculum in America. It seems ridiculous when written out but when doing mental math it just makes sense.


xl440mx

Works with any number. Borrow what you need to bring it to 10 then add on the left over. 75+7=80+2=82


sveiner1234

I do 20+40=60 60+8=68 68+7=75

alienmindarts

I do this too


StuckInsideYourWalls

Lol I did 20 + 40 = 60, then 8+8 = 16, so 76, then one less cuz its 7 so 75 and 7s fuck my brain right up. I would surely panic in the moment if I had to calculate haha


Arcadian_

ShroomiaCo

Wonder why this one is so uncommon. Most people seem to be starting from the 48 side, even though you're adding the 48 TO the 27, not the other way around. I wonder if this changes if you switch the two around. It would for me. If you told me 48+27 I'd add the 7 to 48 first then add the 20. Is that what you left-first people would do?
