1 times table
Every answer is the number you started with. The useful part is knowing why, and where multiplying by 1 turns up later.

How to learn the 1 times table
One group of anything
Multiplying by 1 means taking one group. One group of 8 is 8, so 1 × 8 = 8, and eight groups of 1 is also 8. The answer is always the other number, however large it is: 1 × 250 = 250.
The slip to watch for
The 1 times table is easy to say and easy to get wrong at speed, because adding 1 and multiplying by 1 look alike. 7 + 1 = 8, but 7 × 1 = 7. Zero needs the same care: 7 × 0 = 0, because zero groups of 7 is nothing at all.
Why it matters later
Multiplying by 1 leaves a number unchanged, and that is what makes equivalent fractions work. 2/2, 5/5 and 10/10 are all equal to 1, so multiplying 3/4 by 5/5 gives 15/20: a different-looking fraction with the same value. Division has matching facts. Any number divided by 1 is itself, and any number except zero divided by itself is 1, so 9 ÷ 1 = 9 and 9 ÷ 9 = 1.
Facts worth a second look
- 1 × 1 = 1One group of one. Adding would give 2; multiplying gives 1.
- 1 × 10 = 10One ten. Nothing moves and no zero is added, because there is only one group.
- 1 × 12 = 12One dozen.

Questions about the 1 times table
Why is any number times 1 the same number?
Because multiplying by 1 means taking exactly one group of that number. One group of 6 is 6, so 6 × 1 = 6.
What is 1 × 0?
0. One group of nothing is nothing. Any number multiplied by 0 gives 0.
