Multiplication

3 × 3 = 9

Division

9 ÷ 3 = 3

• Count the rows, then count how many are in each row: 3 rows of 3 makes 3 × 3 = 9.
• As repeated addition that is 3 added 3 times: 3 + 3 + 3 = 9.
• The rows and columns match, so turning this array on its side leaves it unchanged: 3 × 3 = 9 either way.
• That also makes 9 a square number — 3² = 9 — and its square root is 3, because 9 ÷ 3 = 3.
