MATH STUDY GUIDE

Order of Operations

Learning the order of operations is super important and many Math test questions are based on this mathematical concept.

The “operations” are for example: add, subtract, multiply, divide, calculate the square, etc. If something is not a number then it is probably an operation. But, when you see something like … 7 + (6 × 52 + 3). What part would you have to calculate first? Do you start from the left and go to the right? Or from right to left?
