32-8 28+7 15-8 70-24 73-4 16+4 14-7 80-37 56-9 39+7 13-6 50:-26

Let’s calculate each of the expressions:

1. 32 - 8 = 24

2. 28 + 7 = 35

3. 15 - 8 = 7

4. 70 - 24 = 46

5. 73 - 4 = 69

6. 16 + 4 = 20

7. 14 - 7 = 7

8. 80 - 37 = 43

9. 56 - 9 = 47

10. 39 + 7 = 46

11. 13 - 6 = 7

12. 50 ÷ 26 = 1.923 (approximately)

So, the results are:

• 24, 35, 7, 46
• 69, 20, 7, 43
• 47, 46, 7, 1.923 (approximately)
