The 18 times table has 10 multiplication operations. If you understand the patterns in this times table, you can learn these operations easily and calculate quickly!
What Does the Number 18 Mean in Multiplication?
Multiplying by 18 has many approaches. Since 18 = 2 ร 9 = 3 ร 6, you can learn this times table in several ways. Doubling the 9 times table or tripling the 6 times table results in the 18 times table. 18 is important as the age of majority in many countries.
Simple Explanation
When you see 18 ร 4, think: "I have 4 groups and each group has 18 items." So 18 ร 4 = 18 + 18 + 18 + 18 = 72.
Why Is It Important to Learn the 18 Times Table
The 18 times table can be approached from several directions at once, since 18 = 2 ร 9 = 3 ร 6. Doubling the 9 times table, tripling the 6 times table, or using 20รn โ 2รn are all valid, equally correct paths to the same answer. Because every multiple of 18 is also a multiple of 9, the 9 times table's digit-sum rule (digits always add up to a multiple of 9) applies here too, giving students a built-in way to double-check their work.

Patterns in the 18 Times Table
Understanding patterns makes learning easier and more fun. The 18 times table has beautiful patterns that can help you remember it without memorization.
๐18 = 20 โ 2, times n
Since 18รn = 20รn โ 2รn, every 18 times fact can be found by multiplying by 20 and subtracting double the original number: 18ร6 = 120 โ 12 = 108.
๐Digit sums divisible by 9
Because 18 = 2 ร 9, every multiple of 18 is also a multiple of 9 โ so its digits always add up to a multiple of 9: 18ร4=72, and 7+2=9.
โจDouble the 9s or triple the 6s
18 can be reached by doubling the 9 times table or tripling the 6 times table, whichever feels more familiar.

How to Practice the 18 Times Table
Learning times tables requires consistent practice with the right strategies. Here are proven methods to master specifically the 18 times table:
Use 18รn = 20รn โ 2รn: multiply by 20, then subtract double the original number. 18ร6 = 120 โ 12 = 108.
Or double the 9 times table: 18รn = double(9รn).
Or triple the 6 times table: 18รn = triple(6รn) โ pick whichever smaller table you know best.
Check your answer with the digit-sum rule: the digits of an 18 times fact should always add up to a multiple of 9.
Common Mistakes When Learning the 18 Times Table
Many students make similar mistakes when learning this times table. Being aware of these common errors helps you avoid them and learn more effectively.
Subtracting the wrong amount in the 20โ2 trick
Solution: 18รn = 20รn โ 2รn, not 20รn โ 2. Make sure to subtract 2 times the original number, not just 2. 18ร5 = 100 โ 10 = 90.
Confusing 18ร9=162 with 18ร8=144
Solution: The digit-sum check alone won't tell these apart, since both add up to 9. Recompute using 20รn โ 2รn for whichever one you're unsure of.
