Let’s solve each subtraction problem step by step.
We’ll start with the left column:
Subtraction of Eighteen
1. 18 - 1 = 17
2. 18 - 2 = 16
3. 18 - 3 = 15
4. 18 - 4 = 14
5. 18 - 5 = 13
6. 18 - 6 = 12
7. 18 - 7 = 11
8. 18 - 8 = 10
9. 18 - 9 = 9
Now the right column:
Subtraction of Seventeen
1. 17 - 1 = 16
2. 17 - 2 = 15
3. 17 - 3 = 14
4. 17 - 4 = 13
5. 17 - 5 = 12
6. 17 - 6 = 11
7. 17 - 7 = 10
8. 17 - 8 = 9
9. 17 - 9 = 8
All calculations are checked and correct.
Final Answer:
Left Column (Subtraction of Eighteen):
17, 16, 15, 14, 13, 12, 11, 10, 9
Right Column (Subtraction of Seventeen):
16, 15, 14, 13, 12, 11, 10, 9, 8
