Answer :

-198

================

Follow the order of operations.

First, multiply before doing any addition or subtraction:

  • 3 x 400 = 1200

Then apply this result to the rest of the expression:

  • 2 + 1000 - 1200

Simplify the expression by adding and subtracting:

  • 1002 - 1200 = -198

Therefore, the solution to the expression is -198.
