Identify the parts of an algebraic expression.

Objective

Identify the parts of an algebraic expression.

What it means

A term is a number, variable, or product of numbers and variables. A coefficient is the number multiplying a variable. A constant is a term with no variable.

Key terms

Term
A single number or product separated by + or - in an expression.
Coefficient
The numeric factor of a term with a variable.
Constant
A term that is just a number, with no variable.

Rules to remember

  • Terms are separated by + or - signs.
  • A variable with no written number has a coefficient of 1.

Step by step

  1. 1Split into termsBreak the expression at each + or - sign.
  2. 2Label each termSay whether it has a variable (coefficient) or not (constant).

Common mistakes

  • Forgetting a variable with no visible number still has coefficient 1.
  • Miscounting terms when signs are missed.

Tips

  • Read the sign in front of a term as part of that term.
