What Are 3-Step Order of Operations Problems?
A 3-Step Order of Operations problem is similar to the one with 2-steps. There is just another addition to the operator. For example, if in a 2-step Order of Operations problem, the operations of addition and subtraction are used, there may be an inclusion of a multiplication operator in its 3-Step version. Here is how they are solved:
7 x 4^{2} - 5 = 7 x 16 - 5 = 112 - 5 = 107 |
In the example solved above, it can be seen that the exponent is solved first. 42 becomes 16, and then 16 gets multiplied by 7, followed by the execution of subtraction. Here, it is quite evident that PEMDAS or BODMAS rule is applied, and exponents are solved before MDAS. Exponents also include under-roots since they are exponents in fractions. Here is a bit about the 3-Step Order of Operations Problems and how they are solved.
These lessons and worksheets will help students understand how to tackle problems that require three steps to complete.

You will find a completely worked through problem and a nice PEMDAS reminder for you here.

- Homework 1 - To solve all problems that have more than one operation, we use the acronym PEMDAS to tell us the order in which we complete each operation left to right.
- Homework 2 - Now apply this to our problem.
- Homework 3 - We start with the parenthesis first.

#### Practice Worksheets

Remember the steps as you progress through these. They should become second nature by the time you are completed.

- Practice 1 - Remember that exponents come before basic operations.
- Practice 2 - Restate the problem before you complete it.
