A variable expression is simply an expression -- a colllection of values and operators -- that contains at least one "variable" -- which is a quantity whose value has not yet been determined.
For example:
1 + 9/3 is an expression. It can be simplified to a single value, 4.
1 + x is a variable expression. It cannot be simplified to a single value, because 'x' represents an unknown quantity, a quantity that can vary.
