From about fifty to 77 years of age, I have been driven nuts by people and their inability to handle Simple Mathematics. Repeatedly I have witnessed people of both, 2, genders multiply a number such as 5x1=5 and call that five fold... BBBBBBBBBBBSSSSSSSSSS! That is simple multiplication!

So how to teach the simple-minded about Folding! Imagine a piece of paper on a desk. Fold it once and you have 2 layers. Fold that paper twice and there are four layers. Fold it three times and there are eight layers. Fold it four times and there are sixteen layers. Folding a number is not complicated but it is not multiplication.
