What does the word variable mean?

Answer 1

Variable means subject to change, able to vary or differ.

Example : "In summer, the mountain weather was always variable."


In algebra, a variable is a symbol, usually a letter, that represents one or more unknown or changing number.

Example : "The variable is found using the proper equation."

A characteristic number or quantity that increases or decreases over time or takes different situations

Answer 2

It means things that can change. For example, in this problem, x and y are variable:

x*3-2=y

Usually, there is a controlling variable, in this case x. So if I make x 5, it would be:

5*3-2=y

So then y would be 13. Kinda get it?
