4. Вычислите: 60 : 6 80 : 8 (25 + 35) : 10 (47 + 23) : 7 6 - 2 - 2 - 2 8 - 2 - 2 - 2 - 2

Решим примеры по порядку:

1. (60 : 6 = 10)
2. (80 : 8 = 10)
3. ((25 + 35) : 10 = 60 : 10 = 6)
4. ((47 + 23) : 7 = 70 : 7 = 10)
5. (6 - 2 - 2 - 2 = 4 - 2 - 2 = 2 - 2 = 0)
6. (8 - 2 - 2 - 2 - 2 = 6 - 2 - 2 - 2 = 4 - 2 - 2 = 2 - 2 = 0)

Ответы:
* \(60 : 6 = \mathbf{10}\)
* \(80 : 8 = \mathbf{10}\)
* ((25 + 35) : 10 = \(\mathbf{6}\))
* ((47 + 23) : 7 = \(\mathbf{10}\))
* \(6 - 2 - 2 - 2 = \mathbf{0}\)
* \(8 - 2 - 2 - 2 - 2 = \mathbf{0}\)
