Array — 10 × 10 = 100 — free printable diagram

What is 10 × 10?

This array is laid out as 10 rows of 10 dots. Counting every dot gives 100, so 10 × 10 = 100.

Rows

10

Columns

10

Total dots

100

Multiplication

10 × 10 = 100

Division

100 ÷ 10 = 10

• Count the rows, then count how many are in each row: 10 rows of 10 makes 10 × 10 = 100.
• As repeated addition that is 10 added 10 times: 10 + 10 + 10 + 10 + 10 + 10 + … = 100.
• The rows and columns match, so turning this array on its side leaves it unchanged: 10 × 10 = 100 either way.
• That also makes 100 a square number — 10² = 100 — and its square root is 10, because 100 ÷ 10 = 10.
