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.

How to Learn the 18 Times Table (Patterns, Not Memorizing)

Bhanzu teaches the few patterns that generate a table rather than drilling 100 separate facts into a child, so a student builds number sense and the mental agility they carry into algebra instead of flashcard recall that fades. The patterns below all come from what 18 is made of, so you can rebuild any row instead of recalling it. The place-value split is the spine: because 18 is 10 and 8, every product reasons out the same way.

Split 18 as 10 + 8 (place value). This works because $18 = 10 + 8$, so $18 \times n = 10 \times n + 8 \times n$. Take $18 \times 7$: $10 \times 7 = 70$ and $8 \times 7 = 56$, then $70 + 56 = 126$. This is the distributive idea you will meet again in algebra.

Reuse the 9 times table by doubling. Because $18 = 2 \times 9$, the 18s are the 9s doubled, so you lean on a table you already know. $9 \times 5 = 45$, doubled gives $18 \times 5 = 90$; $9 \times 7 = 63$, doubled gives $18 \times 7 = 126$. You can also reason $18 \times n = 20 \times n - 2 \times n$, since $18 = 20 - 2$: $18 \times 6$ is $120 - 12 = 108$.

Understand the digit-sum-9 pattern. The digits of every multiple of 18 add to 9 or a multiple of 9, because 18 is itself a multiple of 9: for $18 \times 4 = 72$, the digits $7 + 2 = 9$. The units digits also step down 8, 6, 4, 2, 0 and repeat, so $18 \times 11 = 198$ ends in 8 again, 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 $120 - 12 = 108$.
