01 / Zero on the end
10 × 7 = 70
Write the number, then write a 0 after it.
Free tool
The 10 times table runs 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120. To multiply a whole number by 10, write a zero after it. Read the table, hide the answers, take a scored quiz, or print a chart or practice sheet. No sign-up and no limit.

How it works
01 / Zero on the end
Write the number, then write a 0 after it.
02 / Place value
Every digit moves one place to the left: ones become tens, tens become hundreds.
03 / Decimals
10 × 3.5 = 35. The decimal point moves one place to the right.
Guide
The 10 times table is 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120 up to 10 × 12. It is quick to learn because the rule is about place value, not memory: multiplying by 10 moves every digit one place to the left. The tool above shows the table, hides answers, runs a scored quiz and prints a chart or sheet.
| Sum | Answer | A way to work it out |
|---|---|---|
| 10 × 1 | 10 | 1 with a zero on the end = 10 |
| 10 × 2 | 20 | 2 with a zero on the end = 20 |
| 10 × 3 | 30 | 3 with a zero on the end = 30 |
| 10 × 4 | 40 | 4 with a zero on the end = 40 |
| 10 × 5 | 50 | 5 with a zero on the end = 50 |
| 10 × 6 | 60 | 6 with a zero on the end = 60 |
| 10 × 7 | 70 | 7 with a zero on the end = 70 |
| 10 × 8 | 80 | 8 with a zero on the end = 80 |
| 10 × 9 | 90 | 9 with a zero on the end = 90 |
| 10 × 10 | 100 | 10 with a zero on the end = 100 |
| 10 × 11 | 110 | 11 with a zero on the end = 110 |
| 10 × 12 | 120 | 12 with a zero on the end = 120 |
In a number like 34, the 3 is worth thirty and the 4 is worth four. Multiply by 10 and each is worth ten times more: 3 becomes three hundred and 4 becomes forty. The zero holds the ones place, so 34 × 10 = 340. This is the same reason 10 × 10 = 100 and 10 × 100 = 1,000.
The rule is the same for decimals. 10 × 3.5 = 35 and 10 × 0.7 = 7. Dividing by 10 is the reverse: 90 ÷ 10 = 9 and 6 ÷ 10 = 0.6. For whole numbers ending in 0, take one zero off.
The ones digit is always 0. The tens digit counts up 1, 2, 3, 4, 5, 6, 7, 8, 9 and then 10 × 10 = 100 gives a hundreds digit. 10 × 11 = 110 and 10 × 12 = 120. Every answer is even, and every answer is a multiple of 5 too.
The 10 table is the base for tricks in other tables. 9 × k is 10k minus k. 11 × k is 10k plus k. 12 × k is 10k plus 2k. 8 × k is 10k minus 2k. If the 10 table feels automatic, those tables become much shorter to learn.
Set Go up to to 20 and the tool shows these as well. For any of them, split the number: 10 × 13 is 10 × 10 plus 10 × 3, which is 100 + 30 = 130.
| Sum | Answer |
|---|---|
| 10 × 13 | 130 |
| 10 × 14 | 140 |
| 10 × 15 | 150 |
| 10 × 16 | 160 |
| 10 × 17 | 170 |
| 10 × 18 | 180 |
| 10 × 19 | 190 |
| 10 × 20 | 200 |
This table needs the rule, not drills. Say it out loud, test a few bigger numbers such as 10 × 35, and take the quiz once to check. Then use the 10 table for tricks in 9, 11 and 12.
Next, try the 11 times table, or go back to the 9 times table. To see every table in one grid, use the times tables chart. To make your own cards, try the flashcard maker.
Questions
10 × 10 = 100.
10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120.
Write a zero after the number. 10 × 8 is 80.
No. For decimals, move the decimal point one place to the right instead. 10 × 0.4 = 4.
Each digit becomes worth ten times more, so it moves one place left. The zero fills the empty ones place.
Yes, because 10 is 5 × 2, so all multiples of 10 are multiples of 5 too.
