40 Times Table
What is the 40 times table?
Answer
Every row of the 40 times table is the row above it plus 40, so the table can be rebuilt from the first line instead of recalled whole. The whole grid from 1 to 10 is on the times table chart.
40 Times Table
| Multiplication | Product |
|---|---|
| 40 × 1 | 40 |
| 40 × 2 | 80 |
| 40 × 3 | 120 |
| 40 × 4 | 160 |
| 40 × 5 | 200 |
| 40 × 6 | 240 |
| 40 × 7 | 280 |
| 40 × 8 | 320 |
| 40 × 9 | 360 |
| 40 × 10 | 400 |
| 40 × 11 | 440 |
| 40 × 12 | 480 |
The table runs to ×12 because that is how far it is taught in Britain; ×10 is where most other school systems stop. The last two rows follow the same rule as the rest, one step at a time.
How to Get the Next Row
A times table is repeated addition written out, so the next row is always the current one plus 40. Nothing has to be remembered except the step.
40 × 1 = 40
40 + 40 = 80 → 40 × 2 = 80
80 + 40 = 120 → 40 × 3 = 120
40 × 12 = 480
Rows that come free
- ×5 is half of ×10: 40 × 5 = 400 ÷ 2 = 200.
- ×9 is ×10 minus the number: 40 × 9 = 400 − 40 = 360.
- ×11 is ×10 plus the number: 40 × 11 = 400 + 40 = 440.
- ×12 is ×10 plus ×2: 40 × 12 = 400 + 80 = 480.
Check It, and What It Is Not
Check by swapping the factors. 40 × 3 = 120 and 3 × 40 = 120 are the same product, so every row of this table appears in another table too, and the two have to agree.
A table is not long multiplication. This page lists one number times 1 to 12; for a product worked out digit by digit, with the carries and the partial products, follow 40 × 12 = 480 into the long multiplication calculator.
The reverse operation is division. Reading the table backwards — 120 ÷ 40 = 3 — is exactly what long division does step by step.
