You don't need to memorize a huge table of calculations in order to figure out what 30% off is.
Yes, you do. Unless you want to take an inordinate amount of time or whip out a calculator. You need to have at least up to 10x10 memorized if you want to do even quick and dirty estimates.
that doesn't mean that someone won't be able to do or understand mathematics; that's just completely insane, and I have no idea how someone could come to such a huge misunderstanding.
I never made such a statement. You could do 3x6 = 6+6+6 every single time and still understand how it all works. You'll stand there in the grocery store like a retard, but you'll eventually get it done.
