Table of 15 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 15 is 15

• Two times 15 is 30

• Three times 15 is 45

• Four times 15 is 60

• Five times 15 is 75

• Six times 15 is 90

• Seven times 15 is 105

• Eight times 15 is 120

• Nine times 15 is 135

• Ten times 15 is 150

What Is the 15 Times Table?

The 15 times table is the list of products you get when you multiply 15 by the whole numbers 1, 2, 3, and onward. Multiplication here is repeated addition, so each row adds one more 15 to the row above it.

That build looks like this:

$15$

$15 + 15 = 30$

$15 + 15 + 15 = 45$

$15 + 15 + 15 + 15 = 60$

Because $15 = 3 \times 5$, every entry is also three times the matching entry in the 5 times table.

Multiples of 15

The first twelve multiples of 15 are:

15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180.

Every entry in the table is a multiple of 15, and every multiple of 15 ends in either 5 or 0 because 15 ends in 5. A multiple is just a number you reach by multiplying 15 by a whole number, so the table and the multiples are the same list written two ways.

How to Learn the 15 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 15 is made of, so you can rebuild any row instead of recalling it. The place-value split is the spine: because 15 is 10 and 5, every product reasons out the same way.

Split 15 as 10 + 5 (place value). This works because $15 = 10 + 5$, so $15 \times n = 10 \times n + 5 \times n$, and the 5-part is always half the 10-part. Take $15 \times 6$: $10 \times 6 = 60$ and $5 \times 6 = 30$, then $60 + 30 = 90$. This is the distributive idea you will meet again in algebra.

Multiply by 30, then halve. Because $15 = 30 \div 2$, you can reason $15 \times n = (30 \times n) \div 2$. Take $15 \times 8$: $30 \times 8 = 240$, halved gives 120. This is quick when the multiplier is even.

Understand why the units flip between 5 and 0. Odd multipliers end in 5, even multipliers end in 0: $15 \times 3 = 45$ ends in 5, $15 \times 4 = 60$ ends in 0. That comes from 15 ending in 5, so a products list that breaks the pattern has an error in it.

How to Read and Use the 15 Times Table

Read a row left to right: $15 \times 6 = 90$ is "fifteen multiplied by six equals ninety." 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 fifteens, chant the rows in order, then test yourself out of order so you are recalling, not reciting. Because 15 also counts the minutes in a quarter-hour, reading a clock face is built-in practice: a quarter past, half past, and quarter to are $15$, $30$, and $45$.

Where the 15 Times Table Appears

Fifteen is a quarter of an hour, so the 15 times table is the arithmetic of clock quarters: every quarter-hour mark, every appointment slot, and every billing block measured in fifteen-minute units lands on a multiple of 15. It shows up in geometry too, where a clock's hour hand sweeps 30 degrees an hour, so it moves 15 degrees in the half-hour and steps through multiples of 15 across the dial. Anyone splitting an hour into quarters is reading off this table.

Solved Examples

Example 1

What is 15 × 4?

Use the multiply-by-10-then-add-half method.

$10 \times 4 = 40$

$5 \times 4 = 20$

$40 + 20 = 60$

Final answer: $15 \times 4 = 60$.

Example 2

A movie ticket costs 15 dollars. How much do 8 tickets cost?

The rusher multiplies by 10 and stops: $10 \times 8 = 80$, writing 80 dollars.

That breaks, because it ignores the extra 5 in each ticket. Eight tickets carry $5 \times 8 = 40$ more than the tens part alone.

Add both parts: $80 + 40 = 120$.

Final answer: 120 dollars.

Example 3

Find 15 × 12.

Halve the 30-times value.

$30 \times 12 = 360$

$360 \div 2 = 180$

Final answer: $15 \times 12 = 180$.

Example 4

15 times what equals 225?

Divide to find the missing factor.

$225 \div 15 = 15$

Final answer: $15 \times 15 = 225$.

Example 5

A meeting runs in 15-minute slots. How many minutes are 14 slots?

$15 \times 14 = (10 \times 14) + (5 \times 14) = 140 + 70 = 210$

Final answer: 210 minutes, or 3 hours 30 minutes.

Common Mistakes

Mistake 1: Stopping after the tens part

Where it slips in: Using $15n = 10n + 5n$ but writing down only the $10n$.

Don't do this: Writing $15 \times 8 = 80$ and forgetting the $5 \times 8 = 40$.

The correct way: Always add both pieces: $80 + 40 = 120$.

Mistake 2: Ending an odd row in 0

Where it slips in: Recalling a row under time pressure and guessing the units digit.

Don't do this: Writing $15 \times 7 = 100$.

The correct way: Odd multipliers end in 5, even multipliers end in 0. Since 7 is odd, the answer ends in 5: $15 \times 7 = 105$.
