Single-digit subtraction
1-Digit Subtraction
Subtract numbers from 1 to 9. Answers run from 0 to 8.
Subtraction and addition undo each other.
Every subtraction fact has an addition fact behind it. To find 9 − 5, ask: 5 plus what makes 9? Because 4 + 5 = 9, the answer is 4.
Addition
- 4 + 5 = 9
- 5 + 4 = 9
Subtraction
- 9 − 5 = 4
- 9 − 4 = 5
4 and 5 are the parts. 9 is the whole. Subtraction starts from the whole and takes away one part.
Two-digit subtraction
Are there enough ones?
Both practices subtract one 2-digit number from another. What differs is whether the starting number has enough ones.
2-Digit Subtraction Without Regrouping
The ones can be subtracted without regrouping. Answers run from 0 to 89.
2-Digit Subtraction With Regrouping
The ones digit of the starting number is smaller than the one below it, so 1 ten is regrouped as 10 ones. Answers run from 1 to 79. Many people call this borrowing.
In 64 − 23 and 64 − 28, only the ones digit of the number subtracted is different.
No regrouping
