Your world would be near impossible for people with sever dyscalculia. I can hardly look at numbers, they almost make me nauseous, and I'm certainly not alone. I won 3 emmy awards though and help build a now publicly traded company. Sure, I can't do math, but boy one day I'd love to teach kids! Also, my wife has a PhD in American History and she teaches it, she's Korean and her English isn't great, but people love her classes.
