A quick way to work it out

Ten times plus two times. For 12 × 7, ten sevens are 70 and two sevens are 14, so the answer is 84. You can also double the table of 6: 6 × 7 = 42, doubled is 84.

Patterns in the table of 12

• Last digit. The last digits run 2, 4, 6, 8 and 0 and then start again, a cycle of five. All of them are even, so no answer in the table of 12 can be odd.
• Odd and even. 12 is even, so every answer is even, whatever you multiply by.
• Digit totals. Add the digits of each answer until one digit is left, and you get 3, 6 and 9, repeating. Only 3, 6 and 9 appear, because 12 is a multiple of 3.
• Steps of 12. Each answer is 12 more than the one above it. So if 12 × 7 slips your mind, take 12 × 6 = 72 and add 12 to get 84.
• Total of the first ten. Add the first ten answers and you get 660. That is 55 × 12, because 1 + 2 + 3 and so on up to 10 is 55.

How the table of 12 is built

12 is not prime: it can be written as 2 × 6 or 3 × 4. So its table can be built from a smaller one. For example 12 × 6 is 3 × 24, and 4 × 6 = 24, so the answer is 3 × 24 = 72. The square of 12 is 12 × 12 = 144. On a multiplication chart the squares lie on the diagonal line from top left to bottom right.

Split it. Above 10, the sure method is to split the number into tens and units. 12 × 8 is 10 × 8 plus 2 × 8, which is 80 + 16 = 96.

Where you meet 12

A dozen is 12, a year has 12 months, a foot has 12 inches and a clock face shows 12 hours. Five dozen bananas are 12 × 5 = 60 bananas, and 7 years are 12 × 7 = 84 months.

Division facts from this table

Every line gives a division fact for free. From 12 × 7 = 84 you know that 84 ÷ 12 = 7 and 84 ÷ 7 = 12. To divide a number by 12, look for it in the answers above: 108 is on line 9, so 108 ÷ 12 = 9. More on this in division from tables.
