Answer 1

To solve the expression 90 - 40(6) + 30, multiply 40 by 6, subtract the result from 90, and then add 30. The correct answer is -120.

Step-by-step explanation:

The question asks to solve the expression 90 - 40(6) + 30. According to the order of operations (PEMDAS/BODMAS), we must first handle the multiplication before doing addition and subtraction.

1. Multiply 40 by 6, which gives us 240.
2. Subtract 240 from 90, which results in -150.
