Order of Operations:

To simplify the expression follow the order of operations: (PEMDAS)

1.      Evaluate the expressions inside the Parenthesis/Brackets (P).

2.      Evaluate Powers/Exponents (E).

3.      Multiply and/or Divide in order from left to right (MD).

4.      Add and/or Subtract in order from left to right (AS). 

A simple technique for remembering the order of operations is turned

into phrase "Please Excuse My Dear Aunty Sally".

The expression is .

                 (Substitute a = 3, b = 0.3, c = and d = )

                        (Product of different signs is negative)

Write the expression as division problem.

Simplify the expression uisng order of operations (PEMDAS).

First operation is evalauating the expression within the parentheses.

                     (Subtract: )

Next operation is division.

                                 (Divide: )     

The value of the expression is 6.
