Learning the Subtraction Tables
There’s only one way to learn the subtraction tables and that is to memorize them. Start on the left and say the equations aloud. Think about the words as you say them. e.g. Two minus one is one, three minus one is two, etc. Once you have them down it’s time to practice.
You can limit the largest number to 4, 6, 8, 10, or 13.
1 - 0 = 1
2 - 0 = 2
2 - 1 = 1
3 - 0 = 3
3 - 1 = 2
3 - 2 = 1
4 - 0 = 4
4 - 1 = 3
4 - 2 = 2
4 - 3 = 1
5 - 0 = 5
5 - 1 = 4
5 - 2 = 3
5 - 3 = 2
5 - 4 = 1
6 - 0 = 6
6 - 1 = 5
6 - 2 = 4
6 - 3 = 3
6 - 4 = 2
6 - 5 = 1

7 - 1 = 6
7 - 2 = 5
7 - 3 = 4
7 - 4 = 3
7 - 5 = 2

8 - 0 = 8
8 - 1 = 7
8 - 2 = 6
8 - 3 = 5
8 - 4 = 4
8 - 5 = 3
