About subtracting 12

The facts for subtracting 12 run from 12 – 12 = 0 to 24 – 12 = 12. Each answer is 12 less than the first number, and adding 12 back gives the first number again: 19 – 12 = 7 and 7 + 12 = 19. Taking 12 from its double leaves 12: 24 – 12 = 12. 12 is 10 + 2, so 20 – 12 is 20 – 10 = 10, then 10 – 2 = 8. One fact family: 12 + 7 = 19, 7 + 12 = 19, 19 – 12 = 7 and 19 – 7 = 12.

Questions and answers

What is on a subtracting 12 worksheet?

Subtraction problems that all take away 12, so 12 is always the second number. At the preset, within 20, the first number is 20 or less and no answer is below zero. The problems come in a mixed order, with a score box and the sheet number.

How do I get every fact from 12 – 12 to 24 – 12?

Choose Within 100 under Numbers. The answers then run from 0 to 12, so the sheet has every fact from 12 – 12 = 0 to 24 – 12 = 12.

How does subtracting 12 link to adding 12?

Each one undoes the other: 7 + 12 = 19, so 19 – 12 = 7. The adding 12 worksheets use the same facts the other way.

Can I take 12 away from bigger numbers?

Yes. Choose Two-digit numbers or Three-digit numbers under Numbers, and 12 is taken away from a number of that size in every problem.

Can a subtracting 12 sheet have borrowing?

Choose With under Regrouping for problems where a column has to borrow a ten, or Without for none. If the numbers chosen have no problem of that kind, the sheet says so and draws any.
