Answer:

The word simplify means make simpler. To simplify an expression is to remove unnecessary numbers or terms, usually by cancelling or factorising. This may apply to working out a numerical problem or grouping together like terms in an algebraic expression in most concise way.

For example, 3p³q x 2pqr = 6p⁴q²r
2(x + 3y) + 3(4x - y) = 2x + 6y + 12x - 3y = 14 x + 3y
