Answer 2

It seems like you've provided a mathematical expression, but the expression is a bit unclear. Let me break it down and try to understand it:

1. (47-7) equals 40.
2. 28 divided by 3 equals 9.3333 (repeating).
3. 5 multiplied by 0 is 0.
4. 1 plus 4492 multiplied by 99.9 equals 449140.1.
5. "дам 25 баллов" appears to be in Russian and translates to "I give 25 points."

So, if we try to make sense of this, it might be:

40, 9.3333, 0, 449140.1, "I give 25 points."

If you have a specific question or need further clarification, please let me know.
