Answer 2

Ответ:

15+7×9=78

53-5×8=13

66-54:6=57

(66-54):6=2

Answer 3

Let's solve each of the equations step by step:

1. 15 + 7 × 9 First, perform the multiplication: 7 × 9 = 63. Then, add 15 to the result: 63 + 15 = 78.

So, 15 + 7 × 9 equals 78.

2. 53 - 5 × 8 First, perform the multiplication: 5 × 8 = 40. Then, subtract 40 from 53: 53 - 40 = 13.

So, 53 - 5 × 8 equals 13.

3. 66 - 54 ÷ 6 First, perform the division: 54 ÷ 6 = 9. Then, subtract 9 from 66: 66 - 9 = 57.

So, 66 - 54 ÷ 6 equals 57.

4. (66 - 54) ÷ 6 First, perform the subtraction: 66 - 54 = 12. Then, divide 12 by 6: 12 ÷ 6 = 2.

So, (66 - 54) ÷ 6 equals 2.

Therefore, both 66 - 54 ÷ 6 and (66 - 54) ÷ 6 are equal to 2.
