Order of Operations with Integers

Order of Operations with Integers

Order of Operations Rule: PEMDAS

• Parentheses-Evaluate within the brackets first

• Exponents-evaluate powers next

• Multiplication and Division next from left to right, first come, first served

• Addition and Subtraction next from left to right, first come, first served

We want to practice using PEMDAS to solve mixed operations problems involving integers

Multiple Choice

The next step in evaluating  $\left(-7\right)+2^3\times3-8$  is

•  $\left(-7\right)+6\times3-8$  

•  $\left(-7\right)+8\times3-8$  

•  $\left(-7\right)+2^3\times-5$  

•  $-3^3\times3-8$  

Multiple Choice

The next step in evaluating  $2\times\left(-7\right)^2+\left(-8\right)-\left(-2\right)$  is 

•  $2\times\left(-7\right)^2-6$  

•  $-14^2+\left(-8\right)-\left(-2\right)$  

•  $2\times49+\left(-8\right)-\left(-2\right)$  

Multiple Choice

The next two steps to evaluate  $\left(-6\right)-10^2\div\left(4+\left(-5\right)\right)=$  

•  $\frac{\left(-6\right)-10^2\div\left(-1\right)}{\left(-6\right)-100\div\left(-1\right)}$  

•  $\frac{-16^2\div\left(4+\left(-5\right)\right)}{-16^2\div\left(-1\right)}$  

Multiple Choice

In evaluating the problem   $\left(\left(-3\right)^2-6\right)\div3\times\left(-10\right)$  
  the line before the final answer is

•  $3\div\left(-30\right)$  

•  $1\times\left(-10\right)$
