Answer 3

Let's break down the expression step by step:

1. $12 + 21 = 33$
2. $33 \times 3 = 99$
3. $609 + 99 = 708$
4. $213.3 - 122.398 = 90.902$
5. $401 - 113.3 = 287.7$
6. $141.2 \times 287.7 = 40554.84$
7. $214314 \times 2 = 428628$
8. $123.3 \times 1000 = 123300$
9. $212.4 + 81 = 293.4$

Now, let's put it all together:

$708 + 90.902 - 40554.84 + 428628 + 123300 - 293.4$

Calculating this, we get:

$708 + 90.902 - 40554.84 + 428628 + 123300 - 293.4 \approx 572,880.662$

So, the result of the given expression is approximately $572,880.662$.

As for your statement about giving 15 points "столбиком" (which means "column" in Russian), I'm not sure what you're referring to. If you have any specific instructions or criteria for grading, please let me know.
