Do you know what an expression is?

shadowlegendx · Answer

3x + x - 9

That is an expression.

Expressions are usually easily identified when you notice that a string of mathematical symbols doesn't have an equals sign(=). The equals sign is a symbol that denotes that string of mathematical symbols as an equation.
