Problem: -23 + 12 · -43 - 32 + 90 = n

Follow the order of PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction)

Sol'n:
-23 + 12 · -43 - 32 + 90
-23 + (-516) - 32 + 90
-23 - 516 - 32 +90
-23 - 516 - (58)
- 23 - 516 + 58
- 23 - 458
- 481

Therefore,
n = -481

Hope this helped. Not sure if this is correct.
