why do we forget math if we don't use it for awhile?

Answer 1

Somebody once told me that a brain keeps everything. It’s just that information gets piled on top of existing information, making it harder to dig up old info.

A good example would be for you to go and pickup a math book and some things will start coming back to you.

Some people use memory techniques that helps them store information forever. Pick up a Mega Memory Book, you will be surprised how easy it is to remember lots of information for a long time.

Answer 2

I've not taken a math course in 2 years, but I still remember enough algebra to be able to help out here. Geometry and calculus, though, are completely gone from my mind. I suppose it's the things that we understood best that sticks, and the stuff we don't, doesn't get stuck.

Answer 3

Yes, but you probably remember certain things when you see them. I've heard that we never forget anything; it's a question of "digging the info out" when you need it!
