The 18 times table from 1 to 20

18 sits beyond the standard 12 × 12 chart, but its multiples come up constantly — a full round of golf is 18 holes. Each row also gives the division fact it answers.

Patterns in the 18 times table

• Last digits. The ones digits repeat every 5 steps: 8, 6, 4, 2, 0, then 8, 6, 4, 2, 0 again. Only 5 different endings ever appear.
• Even answers. 18 is even, so every product in its table is even.
• Digit sums. Keep adding the digits of any answer until one digit is left and you always reach 9 — the test for divisibility by 9.
• Built from a smaller table. 18 = 2 × 9, so every answer is double the matching answer in the 9 times table: 18 × 7 = 2 × 63 = 126.
• Split by place value. 18 × k = 10 × k + 8 × k, so 18 × 13 = 130 + 104 = 234.

A shortcut for multiplying by 18

Twenty times minus twice: 18 × 7 = 140 − 14 = 126.

Worked example: 18 × 7

Split 18 into 10 + 8: 10 × 7 = 70 and 8 × 7 = 56, so 18 × 7 = 126.
