7 and 3 totally look alike! 7 and 2 also look alike. 2 and 3 look alike... they all freakin' look alike! My biggest math issue when I was a kid was my inability to see - + and / (pretend that's an old fashioned division symbol) as DIFFERENT symbols. And I had the weirdest way of solving things:
What's 4/5th's as a decimal?
4 goes into 5... um, once. But then there's a number left over. 1.1? 'Cause there's one left over?
or
100% is 1, right? So if I make the bottom number 100, it'll tell me the right answer... right? 5 and 5 is ten, and 5 and 5 is ten, and 5 and 5 is ten, and 5 and 5 is ten, and 5 and 5 is ten (etc. I'd also circle the tens so I'd know how many there were.) Okay so it takes 10 10s to make 100 which is 20 5s. So what's 20 4s? 80. So 80/100... so what's the decimal of that? 1.8?
Yeah, math was impossible. And even if I DID get the right solution I did so many little steps that it was insanely easy to miscount and then screw up my answer.
