2. Выполни вычисления. 2 ⋅ 9 = ___ 6 ⋅ 2 = ___ 14 : 2 = ___ 16 : 8 = ___ 60 - (37 - 7) = ___ 89 - 56 + 20 = ___

Давай посчитаем:

• \[ 2 \cdot 9 = 18 \]
• \[ 6 \cdot 2 = 12 \]
• \[ 14 : 2 = 7 \]
• \[ 16 : 8 = 2 \]
• \[ 60 - (37 - 7) = 60 - 30 = 30 \]
• \[ 89 - 56 + 20 = 33 + 20 = 53 \]

Ответ:

• \[ 2 \cdot 9 = 18 \]
• \[ 6 \cdot 2 = 12 \]
• \[ 14 : 2 = 7 \]
• \[ 16 : 8 = 2 \]
• \[ 60 - (37 - 7) = 30 \]
• \[ 89 - 56 + 20 = 53 \]
