When I hear people almost brag about not being able to do algebra, I strongly suspect that they can't do long division or multiply without a calculator, add two columns of number that require “carrying”: add, subtract, multiply, and divide mixed fractions or fractions of any kind,;or convert fractions to decimals.

Without paper, I can’t, provided the numbers are large enough. It wasn’t expected of us to take Math in 11th or 12th grade in my high school. Outrageous, I know, although that was 25+ years ago.
