How do you simplify #(2 + 3) + 42 xx (5 − 3)#?
Rather than blindly following PEDMAS, BODMSA, etc in whatever you know it, count the number of term first. Each term will simplify to a single answer and these are added or subtracted in the last step.
In each term the order is:
- brackets first,
- powers and roots
- multiply and divide
