Table of 18 in Words
Saying the table aloud is how most learners lock it in, so here is the spoken form for the first ten rows.
One time 18 is 18
Two times 18 is 36
Three times 18 is 54
Four times 18 is 72
Five times 18 is 90
Six times 18 is 108
Seven times 18 is 126
Eight times 18 is 144
Nine times 18 is 162
Ten times 18 is 180
What Is the 18 Times Table?
The 18 times table is the list of products you get when you multiply 18 by the whole numbers 1, 2, 3, and onward. Multiplication here is repeated addition, so each row adds one more 18 to the row above it.
That build looks like this:
$18$
$18 + 18 = 36$
$18 + 18 + 18 = 54$
$18 + 18 + 18 + 18 = 72$
Because $18 = 2 \times 9$, every entry is also double the matching entry in the 9 times table.
Multiples of 18
The first twelve multiples of 18 are:
18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216.
Every entry in the table is a multiple of 18, and every multiple of 18 is even because 18 itself is even. Each multiple's digits also add to a multiple of 9: for $18 \times 4 = 72$, the digits $7 + 2 = 9$, a quick check that comes from 18 being a multiple of 9.
Tips and Tricks to Memorize the 18 Times Table
There is more than one route in, and the right one depends on which smaller table you already know cold. These four do the most work.
Double the 9 times table. Since $18 = 9 \times 2$, write the 9s and double each product. $9 \times 5 = 45$, doubled gives $18 \times 5 = 90$. $9 \times 7 = 63$, doubled gives $18 \times 7 = 126$.
Multiply by 20, then subtract 2n. Because $18 = 20 - 2$, use $18 \times n = 20 \times n - 2 \times n$. Take $18 \times 6$: $20 \times 6 = 120$ and $2 \times 6 = 12$, then $120 - 12 = 108$. This is fast for bigger multipliers.
Split 18 as 10 + 8. Break 18 into a tens part and an eights part: $18 \times n = 10 \times n + 8 \times n$. Take $18 \times 7$: $10 \times 7 = 70$ and $8 \times 7 = 56$, then $70 + 56 = 126$.
Read the units-digit cycle. The units digits of the first ten multiples step down 8, 6, 4, 2, 0, then repeat. So $18 \times 11 = 198$ ends in 8 again, just like $18 \times 1$.
How to Read and Use the 18 Times Table
Read a row left to right: $18 \times 6 = 108$ is "eighteen multiplied by six equals one hundred eight." The first factor is the group size, the second factor is how many groups, and the product is the total.
To learn it, skip-count aloud in eighteens, chant the rows in order, then test yourself out of order so you are recalling, not reciting. The digit-sum check is a built-in safety net here: if a product's digits do not add up to 9 or a multiple of 9, the answer is wrong.
Where the 18 Times Table Appears
Eighteen is the age of legal adulthood in many countries, so age milestones and voting eligibility tally in eighteens across a population. It shows up on the golf course, where a standard round is 18 holes, so scorecards and course distances scale in multiples of 18. Eighteen is also a common count of items in a carton or tray, so anyone packing in eighteens is reading straight off this table.
Solved Examples
Example 1
What is 18 × 5?
Double the 9-times value.
$9 \times 5 = 45$
$45 \times 2 = 90$
Final answer: $18 \times 5 = 90$.
Example 2
A tray holds 18 muffins. How many muffins are in 6 trays?
The rusher doubles the 8 times table because 18 ends in 8: $8 \times 6 = 48$, doubled gives 96 muffins.
That breaks, because $18 \times 6$ must be more than $9 \times 6 = 54$ doubled, and 96 is short of that.
Double the 9 table instead: $9 \times 6 = 54$, doubled is 108.
Final answer: 108 muffins.
Example 3
Find 18 × 12.
Use the times-20-minus-2n method.
$20 \times 12 = 240$
$2 \times 12 = 24$
$240 - 24 = 216$
Final answer: $18 \times 12 = 216$.
Example 4
18 times what equals 324?
Divide to find the missing factor.
$324 \div 18 = 18$
Final answer: $18 \times 18 = 324$.
Example 5
A golf round is 18 holes. How many holes are played in 15 rounds?
$18 \times 15 = (10 \times 15) + (8 \times 15) = 150 + 120 = 270$
Final answer: 270 holes.
Common Mistakes
Mistake 1: Doubling the wrong table
Where it slips in: Reaching for the 8 times table because 18 ends in 8.
Don't do this: Doubling the 8s, writing $8 \times 6 = 48$ doubled as $18 \times 6 = 96$.
The correct way: Double the 9 times table, since $18 = 9 \times 2$. The correct value is $9 \times 6 = 54$, doubled to 108.
Mistake 2: Subtracting the wrong amount in the 20-minus method
Where it slips in: Using $18n = 20n - 2n$ but subtracting only 2, not $2n$.
Don't do this: Writing $18 \times 6 = 120 - 2 = 118$.
The correct way: Subtract $2 \times n$, not 2. Here $2 \times 6 = 12$, so $120 - 12 = 108$.
