What is #38-8+2(9+3)-:6#?
In addition to using the idea of PEDMAS, BODMAS or whatever form you prefer, the MOST important aspect is to COUNT the number of TERMS first.
Within each term, apply the order of operations:
, then the strongest operations - powers and roots
Then mulitplication and division
Each term stays separate and simplifies to a single answer.
These answers are then added or subtracted in the last line.
Work from left to right.
If there are many terms, it is probably easier to arrange the terms with the adds at the beginning and the subtracts at the end.
