Question

1000·7+(444·7-399·7)-(665·7+353·7)

Answer 1

7000+(3108-2793)-(4655+2471)=7000+(315-7126)=7000-6811=189

Answer 2

To solve the given expression, let's break it down step by step:

1000·7 = 7000 (444·7 - 399·7) = (3108 - 2793) = 315 (665·7 + 353·7) = (4655 + 2471) = 7126

Now let's substitute the values back into the original expression:

7000 + 315 - 7126

Simplifying further:

= -9826

Therefore, the result of the expression 1000·7+(444·7-399·7)-(665·7+353·7) is -9826.
