2 × 8
16
2 rows of 8, or 8 rows of 2: both make 16.
- Turned round
- 8 × 2 = 16
- As division
- 16 ÷ 2 = 8

How this works
Method
The 2 times table is doubling. Two lots of 7 is 7 + 7 = 14, two lots of 12 is 12 + 12 = 24, and any number you can add to itself you can multiply by 2. Full method

Patterns and tricks in the 2 times table
The 2 times table is doubling. Two lots of 7 is 7 + 7 = 14, two lots of 12 is 12 + 12 = 24, and any number you can add to itself you can multiply by 2.
Every answer is even, and the last digits run 2, 4, 6, 8, 0 and then start again: 2 × 6 = 12 ends in 2 just as 2 × 1 = 2 does, and 2 × 9 = 18 ends in 8 like 2 × 4 = 8. Seeing that cycle makes a slip like 2 × 8 = 15 stand out at once, because no double can be odd.
Doubling is the step most other tables are built from. Double a 2-table answer to get the 4 table (2 × 7 = 14, so 4 × 7 = 28), and double once more for the 8 table (8 × 7 = 56). Halving undoes all of it: 18 ÷ 2 = 9.

Frequently Asked Questions
What is the 2 times table up to 12?
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24. Each answer is 2 more than the one before, and each is a number doubled: 2 × 11 = 22 is 11 + 11.
How do I double a bigger number in my head?
Split it into tens and ones and double each part: double 37 is double 30 plus double 7, 60 + 14 = 74. The same works for money, as in double £4.60 = £8 + £1.20 = £9.20.
Why is every answer in the 2 times table even?
An even number is exactly one that splits into two equal whole halves, and 2 × n is two equal parts of n by definition. So the 2 table lists the even numbers in order, and only them.
