Names(Myles)
OBJECTIVES
Students will be able to identify the steps to the order of
operations
Students will be able to follow the steps correctly to
simplify/solve an expression
Students will learn the history of the order of operations
and why we use it and who uses it
Students will identify different sites and games to use to
improve their knowledge of using the order of operations
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 CAREERS USE THE ORDER OF OPERATIONS
Computer programmers
Math text writers
Software developers/writers
Game developers
HOW TO USE THE ORDER OF OPERATIONS
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)
CONCLUSION
What are the steps to order of operations?
Who uses it? Careers?
Why is it important?
