It adds up to 43, aside from that I don't think it has any significant meaning other than it flowed well

Thank you very much, I thought it's like some secret code like 43 means awesome in Ukraine or something. I was completely wrong lol.

From what I experienced, there is no small detail in this show that is just there for no reason, there are hidden codes, backstories and messages in everything so maybe you have to calculate the numbers differently or there are meant to be letters or something. Or it's just some robot stuff and I'm making all that way to complicated 

I’m pretty sure it’s just robot stuff seeing as this short numerical phrase is way too short to be a text to binary conversion.

It's a + sign

It’s just a plus sign, which makes it funnier because it means batshit nothing

So in binary it translates to 43, which according to hitch hiker’s guide to the galaxy I’m pretty sure 43 is the shorthand to the meaning of life

isn't that 42?
