Recall the definition of a variable presented in Section 1.6.

Definition: Variable

A variable is a symbol (usually a letter) that stands for a value that may vary.

Let’s add the definition of a mathematical expression.

Definition: Mathematical Expression

When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.

Thus,

2a, x + 5, and y2,

being formed by a combination of numbers, variables, and mathematical operators, are valid mathematical expressions. A mathematical expression must be well-formed. For example,

2 + ÷5x

is not a valid expression because there is no term following the plus sign (it is not valid to write +÷ with nothing between these operators). Similarly,

2 + 3(2

is not well-formed because parentheses are not balanced.
