Answer 2

It seems like you've provided a series of mathematical operations. Let's break it down step by step:

1. $52 \div 4 = 13$
2. $90 - 8 = 82$
3. $57 \div 6 = 9.5$ (or $19 \div 2 = 9.5$ if you're considering only integers)
4. $(30 - 15) = 15$
5. $5 \times 17 = 85$
6. $65 \div 20 = 3.25$ (or $13 \div 4 = 3.25$ if you're considering only integers)

After this, you've provided a series of operations that are not clear. It looks like you have a combination of multiplication, addition, and division, but it's not in a standard mathematical format.

If you could clarify the operations and provide them in a more standard format, I'd be happy to help you further!

Answer 3

It seems like you've provided a series of mathematical operations. Let's break them down step by step:

1. 52 : 4 = 13

2. 90 - 8 = 82

3. 57 : 6 = 9

4. (ост. 30 - 15 = 15) - It appears that there's an operation in parentheses that wasn't executed. Let's assume it's subtraction. So, 15 - 17 = -2

5. 65 : 20 = 3

6. (ост. 2 - 28) + (9355 x 257) = -26 + 2406135 = 24061109

The final result is 24061109.

If I misunderstood any part of your question or if there's a different interpretation you intended, please clarify, and I'll be happy to help further.
