FACTS ABOUT SUBTRACTION
1. Subtraction with small numbers can be worked out horizontally.
Example:
8 – 5 = 3
24 – 4 = 20
2. Subtraction with large numbers is worked out vertically. Numbers are written under the place value chart.
Example: Th H T O
8 6 7 2
- 5 4 3 2
3 2 4 0
3. Zero subtracted from a number does not change the value of the number.
Example: H T O
2 5 8
+ 0
2 5 8
