INTRODUCTION

You ever wondered what might happen if you tried to eat a cake before you baked it, or drive a car before turning it on or even what might happen if you went straight to the 12th grade without passing the first 11?

All these are things that need to be done in a specific order before they can be completed.

This is the same way you have to simplify a specific expression in Math using “The order of operations.”

HISTORY

A long time ago, people just decided on an order in which operations should be performed. It has nothing to do with magic or logic. Some people decided to adopt a way, and it has stuck ever since. It just makes communication a lot easier. Another way of saying this is that rather than being inherent in the structure of mathematics, the concept of "order of operations" is a matter of mathematical notation. Order of operations refers to which operations should be performed in what order, but it's just convention. The notation tells you which operations to do first, not something about the underlying mathematics.

WHY IMPORTANT

Studying the order of operations and the laws governing the use of operations will permit us to apply them to solve problems and get correct data. If we do not master operations and the rules for their application, we can't work problems in a clear and consistent manner to arrive at the right answers.

WHAT CAR EERS US E THE O RDER OF OPERATION S

Computer programmers

Math text writers

Software developers/writers

Game developers

HOW TO USE THE O RDER OF OPERATION S

Think of PEMDAS to get you started with the steps

1. Do parenthesis first

2. Simplify all exponents and Radicals

3. Multiply and/or divide from left to right

4. Add/Subtract from left to right

EXAMPLE

9 + 2 2 + 3 x 2

9 + 1 + 6

10 + 6

16

NOW YOU TRY

4 + 5 x 3 – 10 + (15 – 8)
