How do you simplify #17– 6 xx 10 ÷ 2 + 12#?
Using PEMDAS rule,
Identify the number of terms first. Each term will simplify to a single answer which can be added or subtracted in the last step.
Within each term the order of operations is:
- powers and roots
- multiplication and division (any order)
You will make fewer mistakes if you write the additions at the beginning and subtractions at the end.
