Multiplication

8 × 8 = 64

Division

64 ÷ 8 = 8

• Count the rows, then count how many are in each row: 8 rows of 8 makes 8 × 8 = 64.
• As repeated addition that is 8 added 8 times: 8 + 8 + 8 + 8 + 8 + 8 + … = 64.
• The rows and columns match, so turning this array on its side leaves it unchanged: 8 × 8 = 64 either way.
• That also makes 64 a square number — 8² = 64 — and its square root is 8, because 64 ÷ 8 = 8.
