To evaluate expressions using the correct order of operations, you need to learn the order of operations. The correct order of operations is PEMDAS.

Here’s what PEMDAS stands for:

   for x=2

              

 

         

                

 

 

    

     


Now you try

 

1)      when x= -3

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

                2)  when x=3

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

             3) when x=3

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

      4)when x=4

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

   5)  when x=2
