Реши удобным способом. 22 + 17 + 8 + 13 = 11 + 19 + 1 + 39 = 44 + 4 + 6 = 50 + 17 + 30 =

Решение:

1. \(22 + 17 + 8 + 13 = (22+8) + (17+13) = 30 + 30 = 60\)
2. \(11 + 19 + 1 + 39 = (11+19) + (1+39) = 30 + 40 = 70\)
3. \(44 + 4 + 6 = 44 + (4+6) = 44 + 10 = 54\)
4. \(50 + 17 + 30 = (50+30) + 17 = 80 + 17 = 97\)

Ответ: 60, 70, 54, 97
