What does algebrac expression mean?

Answer 1

An algebraic expression is a way of recording or communicating a general idea or quantity. For example, if we want to say how many gloves we need in order to to give gloves to five people, that's 2 x 5 gloves = 10, but if we want to say how many gloves anynumber of people need, we say it's two times the number of people. This is an algebraic expression. It doesn't specify how many people there are. A more usual algebraic way of writing the number of gloves needed would be 2p, where p stands for the number of people. 2p means 2 x p. We don't usually bother to write the multiplication sign.
