Think in tens
Ten equal groups turn each whole-number unit into a ten. Ten groups of twelve are twelve tens: one hundred and twenty. For the whole numbers in this table, writing a zero after the number gives the product.
10 × 12 = 120

Check your reasoning
This page uses whole numbers 1–12. The underlying idea is place value; avoid treating “add a zero” as a rule for every kind of number.
Neighbouring facts differ by 10. If you know 10 × 6 = 60, add 10 to find 10 × 7: 60 + 10 = 70.
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.
10 × 3 = ?
10 × 3 = 30. Reversing the factors gives 3 × 10 = 30 too.
10 × 7 = ?
10 × 7 = 70. Reversing the factors gives 7 × 10 = 70 too.
10 × 8 = ?
10 × 8 = 80. Reversing the factors gives 8 × 10 = 80 too.
10 × 11 = ?
10 × 11 = 110. Reversing the factors gives 11 × 10 = 110 too.
10 × 12 = ?
10 × 12 = 120. Reversing the factors gives 12 × 10 = 120 too.
