Parentheses

5.OA.A.1

Definition

Grouping symbols ( ) that show which part of an expression to calculate first.

Examples

  • (2 + 3) x 4 = 20, since the parentheses are done first.
  • 2 + (3 x 4) = 14, since multiplication inside the parentheses comes first.

Key rule

Always do the operation inside parentheses first.

Memory hook

Parentheses go first, no matter what.
