Ordering Operation

Q:99*(57+76)*9-1085/9

Hi Garrett

The convention for the order of operations is:

  1. Operations that are inside Parentheses

  2. Powers (Exponents)

  3. Division and Multiplication

  4. Addition and Subtraction
(some people remember this as PEDMAS.)

In your problem perform (57+76) first to get

99*(57+76)*9-1085/9
=99*133*9-1085/9

There are no exponents so perform the multiplications and division

99*133*9-1085/9
=89899-120.556

And finally the subtraction

89899-120.556
=89778.44
