D  Division

A  Addition

S  Subtraction

 

Here’s an example of how we can get different answers if the correct order of operations is NOT followed.

Expression solved from Left to Right

6 x 3 + 4 x ( 9 ÷ 3 )                        

6 X 3 + 4 x ( 9 ÷ 3 )

18 + 4 x ( 9 ÷ 3 )  

22 x ( 9 ÷ 3 )

198 ÷ 3

= 66     ✘

Expression solved using Order of Operations (PEMDAS)  

6 x 3 + 4 x ( 9 ÷ 3  )

6 X 3 + 4 x ( 9 ÷ 3 ) → P

6 X 3 + 4 x 3 → M

18 + 4 x 3 → M

18 + 12 → A

= 30     ✔
