Multiplication

2 × 2 = 4

Division

4 ÷ 2 = 2

• Count the rows, then count how many are in each row: 2 rows of 2 makes 2 × 2 = 4.
• As repeated addition that is 2 added 2 times: 2 + 2 = 4.
• The rows and columns match, so turning this array on its side leaves it unchanged: 2 × 2 = 4 either way.
• That also makes 4 a square number — 2² = 4 — and its square root is 2, because 4 ÷ 2 = 2.
