 - 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 x (8 + 7). Recognize that 3 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
