The 18 times table
Eighteen is 9 doubled, so the 9s tricks have a twin here.
- 18×1=18
- 18×2=36
- 18×3=54
- 18×4=72
- 18×5=90
- 18×6=108
- 18×7=126
- 18×8=144
- 18×9=162
- 18×10=180
- 18×11=198
- 18×12=216
How to learn the 18s
Each line means “18 groups of”. So 18 × 4 = 72 means four groups of 18 make 72. Every answer is just 18 more than the one before: 18, 36, 54, 72, 90…
The highlighted facts, 18 × 6 = 108, 18 × 7 = 126, 18 × 8 = 144 and 18 × 12 = 216, are the ones learners usually find hardest. The tips below give you a way into each one.
Self-test: press “Hide answers”, say each answer out loud, then tap a fact to check it.
In real life
A golf course has 18 holes. Playing it twice is 18 × 2 = 36 holes.
Three ways to make the 18s easy
Double the 9s
Find the 9s answer, then double it.
9 × 7 = 63 → 18 × 7 = 126Twenty minus two
18 is 2 less than 20. Work out 20 × the number, then take away two of it.
18 × 6 = 120 − 12 = 108The digit check
Keep adding the digits of an 18s answer until one digit is left — you always get 9.
18 × 7 = 126 → 1 + 2 + 6 = 9Spot the pattern
Last digits of 18 × 1 to 18 × 10:
Endings count down by 2. 18, 36, 54, 72, 90: the last digits go 8, 6, 4, 2, 0 — like the 8s.
Every other 9. Count in 9s and keep every second answer: 9, (18), 27, (36), 45, (54).
The matching division facts
Every multiplication fact gives you a division fact for free. If 18 × 6 = 108, then 108 ÷ 18 = 6.
- 18 ÷ 18 = 1
- 36 ÷ 18 = 2
- 54 ÷ 18 = 3
- 72 ÷ 18 = 4
- 90 ÷ 18 = 5
- 108 ÷ 18 = 6
- 126 ÷ 18 = 7
- 144 ÷ 18 = 8
- 162 ÷ 18 = 9
- 180 ÷ 18 = 10
- 198 ÷ 18 = 11
- 216 ÷ 18 = 12
