I know how it might feel though. I can do arithmetic without pain and didn't have trouble with some high school and college math, but logic and analysis of problems causes a sort of pre-headache which does go full blown if I try to proceed straight forwardly. I have to sort of "not think" and play with the parts of problems. Did competent software for around 30yrs. I do love calculators. S
It's not arithmetic that hurts me ....
