Mathematics / Numerical Expressions

5.OA.1. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
5.OA.2. Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. 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.
