Understanding Subtraction with Numbers up to 10
Use simple examples such as:
- 5 – 3 = 2 (Start with 5 and take away 3, leaving 2).
Basic Subtraction Facts
Facts to memorize:
- 10 – 1 = 9
- 9 – 2 = 7
- 8 – 3 = 5
- 7 – 4 = 3
- 6 – 5 = 1
Zero in Subtraction
- Any number minus zero remains the same: 5 – 0 = 5.
- Subtracting a number from itself gives zero: 5 – 5 = 0.
Learn with an example
🚀Subtract. 8 – 7 =
- You can count on to find 8 – 7. Start at 7. Count on until you reach 8.
- You counted on 1 time.
- 8 – 7 = 1
🚀Subtract. 9 – 5 =
- You can count back to find 9 – 5. Start at 9 and count back 5 times.
- You end at 4.
- 9 – 5 = 4
🚀Subtract. 6 – 6 =
- When you subtract a number from itself, the answer is zero.
- 6 – 6 = 0
- You can count back to show this. Start at 6 and count back 6 times.
- You end at 0.
- 6 – 6 = 0
