<PRE><B>Question 142016</B>
Simplify the following expressions using PEMDAS.

2 + 3 ´ 52 - 7
Comment: What is happening between 3 and 52 ?
----------------------- 
6 + 3[(12 / 4) + 5] 
= 6 + 3[3+5]
= 6 + 3[8]
= 6 + 24 
= 30
-----------------
(4 / 2) + 4(5 - 2)^2
= (2) + 4(3)^2
= 2 + 4(9)
= 2 + 36
= 38
--------------- 
-8 - 81 / 9 ´ 22 + 7
Comment: What is happening between 9 and 22 ?
