   ORDER OF
OPERATIONS                   
 

 
  When solving equations or doing any computations. You must follow the rules concerning the order in which each operation takes place.

1st. Any operation in brackets eg. (2+3).   { note: (inner most brackets (like this first))}
2nd. Exponents (see module 2)
3rd. Multiplication or Division (whichever comes first from left to right).
4th. Addition or Subtraction  (whichever comes first from left to right).
 

 
   
Note An addition is performed before a subtraction only if it appears before the subtraction moving from left to right.
The same applies for multiplication and division since it depends which operation appears first moving left to right.
 
Note If an equation or expression contains more than one pair of grouping symbols (brackets), start operating within the innermost pair outwards as in this example:
 7 + {25 - 3 * (
4 + 1)}   =  7 + {25 - 3 * 5}    =  7 + {25 - 15}    =  7 + 10    =  17
 
  Problem Solving 
Read the question carefully and determine if the operation or action requires an addition, a
subtraction, multiplication, division or combination of all these to be done.
Determine what operations must be done first and simply find the result.
