Answer 1

1) (2928-88):142=2840:142=20
2) 15732:57:(156:13)=15732:57:12=23

Answer 2

1) (2928-88) + : 1422

To solve this expression, we need to perform the operations in the correct order. The first step is to subtract 88 from 2928, which gives us 2840. Then, we add the result to 1422.

So, the solution to (2928-88) + : 1422 is 4262.

2) 15 + 732 : 57 + : (156:13)

To solve this expression, we need to follow the order of operations, which is parentheses, multiplication and division (from left to right), and then addition and subtraction (from left to right).

Let's break it down step by step:

1. Inside the parentheses, we have 156 divided by 13, which equals 12.

2. Next, we have 15 + 732 divided by 57. Performing the division first, we get 732 divided by 57, which equals 12.8421 (rounded to four decimal places). Then, we add 15 to this result, giving us 27.8421 (rounded to four decimal places).

So, the solution to 15 + 732 : 57 + : (156:13) is approximately 27.8421.
