- An algebraic expression is a group of variables and numbers joined together with +, -, x or divide signs; m + 2, 3x + 5y, 7xy - 3 are all algebraic expressions.
- Each part of an expression is called a term. The expression 3x + 5y has two terms: 3x and 5y.
- The number in front of a term is called a coefficient. In the expression 3x + 5y, 3 is the coefficient of x, and 5 is the coefficient of y.
- A number without a variable is called a constant term. In the expression 4x + 7, the number 7 is a constant term.
