Double the number

Two equal groups make a double. If one row has seven seats, two rows have 7 + 7 = 14 seats. Use a familiar addition fact to find the product.

2 × 7 = 7 + 7 = 14

Check your reasoning

Every answer is even, but that alone does not identify it. For 2 × 8, check that you doubled eight rather than added two.

Neighbouring facts differ by 2. If you know 2 × 6 = 12, add 2 to find 2 × 7: 12 + 2 = 14.

Try it yourself

Say or write an answer before opening each question. If you get stuck, use the method above, then try that fact again later without looking.

2 × 3 = ?

2 × 3 = 6. Reversing the factors gives 3 × 2 = 6 too.

2 × 7 = ?

2 × 7 = 14. Reversing the factors gives 7 × 2 = 14 too.

2 × 8 = ?

2 × 8 = 16. Reversing the factors gives 8 × 2 = 16 too.

2 × 11 = ?

2 × 11 = 22. Reversing the factors gives 11 × 2 = 22 too.

2 × 12 = ?

2 × 12 = 24. Reversing the factors gives 12 × 2 = 24 too.
