Algebra is required for admission to most colleges.

The word algebra comes from the Arabic al-jabr, which means "the reduction."

If n is a whole number,
2n
is always an even number
and 2n + 1 is always odd.

The Greek mathematician Diophantus (about 250 AD) is sometimes called the father of algebra.
