Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

Partial match Proposed 30%

5.OA.A.2

Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. <em>For example, express the calculation "add 8 and 7, then multiply by 2" as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.</em>
