The issue here is that the memory aid only deals with exponents and the 4 binary operations; the negation (opposite) involved here is outside of the rule.
Is Pemdas always the rule?

What are two step problems?
Two-step word problems can be difficult to solve as the student needs to work out what should be solved first and then determining and solving both steps. Most two-step word problems that involve multiplication have a multiplication step and an addition or subtraction step.
What are the key words for multiplication?
