Answer 1

1) 1469

2)1503

3)757

4)64

5)638, но если там деление вместо точки, то ничего не будет, а если умножение, то будет 212

6) если деление вместо точки, то 0, если это десятичная дробь, то 777,8

Answer 2

Let's break down the given expression step by step:

1. 1238 + 462 = 1700
2. 21824 - 963 = 20861
3. 3936:6 = 656
4. 445684:2 = 222842
5. 278848:4 = 69712
6. 426.0888.8 is not a valid number format; it seems there might be a typo or formatting error.
7. 666:6 = 111
8. 426.0888.8-666:6 is not valid due to the issues in the previous step.

Since there are formatting errors and ambiguities in the expression you provided, I can only provide calculations for the parts that are clear. Please correct any typos or formatting errors, and I'll be happy to help you further.
