Well, if you pay by card, you're not going to get ripped off unless the merchant with the POS (Point of Sale) mis-keys it. That's why chip+pin, tap-to-pay and apple-pay show you the amount you're being charged and you should never hand your card to someone. If you must use the swipe, you swipe yourself.

Getting paid or doing shopping doesn't require you to use math. Come to think of it, all the math I really use outside of programming/spreadsheet/graph abuse (literately I generate graphs out of numbers that people can't understand) is when adding gratuities to the restaurant bill, or buying items in quantities at the store, and double-checking that whatever discount applied is on the actual receipt at the self-checkout. One time in the last 3 years was something wrong. Prior to that, I had been overcharged by 100$ by a restaurant about 10 years prior, because the merchant mis-keyed 10.00 as 110.00 and I saw it briefly when I used the card, but it didn't register in my mind what was wrong until I checked the receipt when I got home. That was a three month ordeal that I wound up with 100$ in gift certificates for.

Suffice it to say, even when we use math, sometimes we are so used to things just working that when they go wrong it's just not going to register. With the advent of Apple Pay, you actually see the amount you are being charged on your device, even if you use those cards without using apple pay. So now you have a "you paid X.XX to BUSINESS NAME" message sitting on the phone/ipad when you get home if you forgot to take it with you.
