The Order of operations

Part I-Teach someone else

Dear Friend,

I've gotten wind of your predicament concerning things such as: The Order of Operations, what they are, and all of their facets, among a few other things. I believe I can help you out with this, and took the liberty of explaining a few things concerning the aspects of the Order of Operations in the following parts of this letter. A) What Operation Symbols Do You Know ?

The Operation Symbols that are needed for a person to be familiar with are Muliplication, Division, Addition, and Subtraction. B) What Grouping Symbols Do You Know ?
The Grouping Symbols that you are needed to know are the parenthesis and the brackets. C) What is the "Order of Operations" ?
The Order of Operations consists of (in a nutshell): Multiplication, Division, Addition, and Subtraction (in that specific order). This can be mentally compressed into "My Dear Aunt Sally". D) Why is the "Order of Operations" Important ?

The Order of Operations is important because, without it, we would have no definite shape or way of how to formulate answers and relate them to each other on a consistent basis. E) What is the order of use for the grouping symbols ?

You must remember to work "From the inside, out".
F) What do exponents mean ?
Exponents symbolize to what value, or, power, if you may, you add to your main number. It is the ‘simplified' form of instructing what to multiply the main number by. G) How can the phrase, "Please Excuse My Dear Aunt Sally" help a student remember the Order of Operations ? It is, in essence, an easier way for the brain to remember the Order of which to Operate: Parentheses for Please, Exponents for Excuse, Multiply for My, Divide for Dear, Add for Aunt, and Subtract for Sally.

Well friend, with that I'll be off, if you have any more questions, don't hesitate to ask!

Your Name
