Is NOBODY wrong in the post ? POST : Apologies for any formatting issues, mobile user here, also spelling isn’t my strong suit.
Long-ish post, TLDR right here for convenience

TLDR: gf and I arguing, tell her +/- numbers under ten is something she should be able to do, calls me an ass, am I? 

I’d like to preface this by saying a persons education is not something they should apologize for. My GF also has some issues with dyslexia and ADD. 

My GF works in customer service, is a high school graduate, and deals with numbers daily. Lately we have been having an increasing amount of arguments stemming apparently from me nit picking her about several things.

Though I see these things as something she should know, she feels different, and usually responds in an aggressive way (yelling at me).

One of the biggest issues is that she can’t seem to do simple math without a calculator or hand counting. And by simple math I mean adding and subtracting numbers UNDER TEN!

When I told her this is defiantly something she should be able to do, she called me an A$$ and said she “just can’t learn it!”

There is a lot more to this but the jist of it is here.

So AITA?
