Question

15+(90-9):3=17. (9×4-6×5)×4-42:7+(60-11)

Answer 1

прости только со вторых скобок

1)9*4=36

2)6*5=30

3)36-30=6

4)60-11=49

5)6*4=24

6)42:7=6

7)24-6=18

8)49+18=67  

Answer 2

Let's break down the calculations step by step:

1. Start with the first equation: 15 + (90 - 9) / 3
   • Inside the parentheses, 90 - 9 equals 81.
   • Then, divide 81 by 3, which equals 27.
   • Finally, add 15 to 27, resulting in 42.

So, the first equation simplifies to 42.

2. Now, let's evaluate the second equation: (9 × 4 - 6 × 5) × 4 - 42 / 7 + (60 - 11)
   • Inside the first set of parentheses, 9 × 4 equals 36, and 6 × 5 equals 30. So, 36 - 30 equals 6.
   • Then, multiply 6 by 4, which equals 24.
   • Next, inside the second set of parentheses, 60 - 11 equals 49.
   • Inside the last set of parentheses, the previously calculated result is 42.
   • Now, divide 42 by 7, which equals 6.
   • Finally, perform the remaining operations: 24 - 6 + 49 equals 67.

So, the second equation simplifies to 67.

To summarize:

• The first equation, 15 + (90 - 9) / 3, equals 42.
• The second equation, (9 × 4 - 6 × 5) × 4 - 42 / 7 + (60 - 11), equals 67.
