Division

121 ÷ 11 = 11

• Count the rows, then count how many are in each row: 11 rows of 11 makes 11 × 11 = 121.
• As repeated addition that is 11 added 11 times: 11 + 11 + 11 + 11 + 11 + 11 + … = 121.
• The rows and columns match, so turning this array on its side leaves it unchanged: 11 × 11 = 121 either way.
• That also makes 121 a square number — 11² = 121 — and its square root is 11, because 121 ÷ 11 = 11.
