1. Выполни вычисления. 4+7= 9+3= 13-4= 17-9= 8+6= 9+7= 7+6= 11-5= 16-9= 12-5= 15-8= 13-6= 5+9= 14-7= 3+8= 9+4=

Решение:

Выполняем вычисления:

1. \( 4 + 7 = 11 \)
2. \( 9 + 3 = 12 \)
3. \( 13 - 4 = 9 \)
4. \( 17 - 9 = 8 \)
5. \( 8 + 6 = 14 \)
6. \( 9 + 7 = 16 \)
7. \( 7 + 6 = 13 \)
8. \( 11 - 5 = 6 \)
9. \( 16 - 9 = 7 \)
10. \( 12 - 5 = 7 \)
11. \( 15 - 8 = 7 \)
12. \( 13 - 6 = 7 \)
13. \( 5 + 9 = 14 \)
14. \( 14 - 7 = 7 \)
15. \( 3 + 8 = 11 \)
16. \( 9 + 4 = 13 \)

Ответ: 11, 12, 9, 8, 14, 16, 13, 6, 7, 7, 7, 7, 14, 7, 11, 13.
