Question

What are variable expressions?

Answer 1

Variable expressions are expressions that involve variables, which are symbols that represent changing quantities. (See http://socratic.org/questions/what-are-variables for reference). The value of the expression will change as the value of the variable changes.

For example, let's say with have the equation `x + 5`

When `x = 1`, then `x + 5 = 6`

When `x = 2` then `x+5 = 7`
