An "expression" is anything that can be evaluated into a number. That includes variables; if you replace them with values, you can get a number. Here are some example:
5 (numbers themselves are expressions)
x (a simple variable)
5+3 (a sum)
x+3 (a sum involving variables)
3y (a product involving variables)
5x2 + 3x - 2 (a polynomial)
sin(x) (a mathematical function)
