Ответ:
Решение:
- \( 42 + 18 - 40 = 60 - 40 = 20 \)
- \( 18 + 26 + 16 = 44 + 16 = 60 \)
- \( 80 - 34 + 16 = 46 + 16 = 62 \)
- \( 42 - 26 + 50 = 16 + 50 = 66 \)
- \( 53 + 37 - 66 = 90 - 66 = 24 \)
- \( 42 + 48 - 16 = 90 - 16 = 74 \)
- \( 48 - 37 + 79 = 11 + 79 = 90 \)
- \( 54 + 17 + 19 = 71 + 19 = 90 \)
Ответ: 20, 60, 62, 66, 24, 74, 90, 90.
