Question

30+(46-12)=45+(67-60)=? 63-(59-49)=98-(24+22)=?

Answer 1

Ответ:

Пошаговое объяснение:

30+(46-12)=30+34=64

45+(67-60)=45+7=52

63-(59-49)=63-10=53

98-(24+22)=98-46=52

Answer 2

Let's break down the calculations step by step:

1. 30 + (46 - 12): First, we solve the expression within the parentheses: 46 - 12 = 34. Then, we add 30 and the result: 30 + 34 = 64.

2. 45 + (67 - 60): Within the parentheses, 67 - 60 = 7. Adding 45 and 7 gives us: 45 + 7 = 52.

3. 63 - (59 - 49): Similar to the previous examples, we solve the expression within the parentheses: 59 - 49 = 10. Now, we subtract 10 from 63: 63 - 10 = 53.

4. 98 - (24 + 22): First, we perform the addition within the parentheses: 24 + 22 = 46. Then, we subtract 46 from 98: 98 - 46 = 52.

Therefore, the answers to the given equations are:

1. 30 + (46 - 12) = 64
2. 45 + (67 - 60) = 52
3. 63 - (59 - 49) = 53
4. 98 - (24 + 22) = 52
