What is the product of 5 and 7?

Mathematical Equivalence

ON

Answer explanation

Strategies to multiply and divide:

1. Array Model: Use an array (a set of rows and columns) to visualize multiplication. For example, to solve 3 x 4, create 3 rows of 4 dots. Count the total dots to find the answer (12).

3. Skip Counting: Count by the same number to find products. For 5 x 3, skip count by 5s: 5, 10, 15. The answer is 15.

5. Using Fact Families: Understand that multiplication and division are related. For 2 x 6 ₌ 12, you can also say 12 ÷ 6 ₌ 2. This helps prove both operations.

7. Distributive Property: Break numbers into smaller parts. For 4 x 6, think of it as (4 x 5) plus (4 x 1) equals 20 + 4 ₌ 24.

9. Repeated Addition: For multiplication, think of it as adding the same number multiple times. For 3 x 4, add 3 + 3 + 3 + 3 = 12.

11. Repeated Subtraction: For division, think of it as subtracting the same number multiple times. For 12 ÷ 4, subtract 4 from 12 until you reach zero: 12 - 4 - 4 - 4 = 0. Count how many times you subtracted (3).
