When you are trying to understand new math concepts, it helps immensely to see the equivalency in your head. If you can do calculations, then factoring is a whole lot easier. If you can’t factor in your head, then you probably won’t understand factors. If you can do calculations, then finding the least common denominator is child’s play. If you can’t you probably won’t intuitively understand why the LCD is important.

Nobody is going to understand how to factor binomial equations if they can’t figure out how much to tip a waiter without the aid of a calculator.

What’s more, math calculation sharpens the mind, teaches focus, concentration and stamina. It provides a real source of self-esteem to kids, who can demonstrate that they can do something perceived as difficult. It is an accomplishment.
