4.OA. Operations and Algebraic Thinking
4.OA.A. Use the four operations with whole numbers to solve problems.
4.OA.A.1. Use and interpret multiplicative equations.
4.OA.A.1.a. Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal or written statements of multiplicative comparisons as multiplication equations. Example: Tom has 7 toy cars; Joe has 5 times as many. How many toy cars does Joe have? Answer: 35, because 7 x 5 = 35 or 5 x 7 = 35.
