About subtracting 1

The facts for subtracting 1 run from 1 – 1 = 0 to 13 – 1 = 12. Each answer is 1 less than the first number, and adding 1 back gives the first number again: 8 – 1 = 7 and 7 + 1 = 8. Taking 1 from its double leaves 1: 2 – 1 = 1. Taking 1 from 10 leaves 9: 10 – 1 = 9. One fact family: 1 + 7 = 8, 7 + 1 = 8, 8 – 1 = 7 and 8 – 7 = 1.

Questions and answers

What is on a subtracting 1 worksheet?

Subtraction problems that all take away 1, so 1 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 1 – 1 to 13 – 1?

Choose Within 100 under Numbers. The answers then run from 0 to 12, so the sheet has every fact from 1 – 1 = 0 to 13 – 1 = 12.

How does subtracting 1 link to adding 1?

Each one undoes the other: 7 + 1 = 8, so 8 – 1 = 7. The adding 1 worksheets use the same facts the other way.

Can I take 1 away from bigger numbers?

Yes. Choose Two-digit numbers or Three-digit numbers under Numbers, and 1 is taken away from a number of that size in every problem.

Can a subtracting 1 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.
