One thing that I learned with order of operations is that it's so easy to just do any problem from left to right without looking for symbols, especially problems like 1+3x7. Before just doing problems, you should look for changing symbols, even if their not obvious.

Hi everyone! One thing I learned from Order of Operations is that it is a very easy way to simplify a complex problem. If you break it down into smaller sections, the problem won't appear very hard.

Another thing I learned is that, with multiplication and division, it doesn't matter which order you add or multiply, just so long as it is ONLY multiplication or division.

Do yourself a favor and follow the rules. If you do the Order Of Operations right the first time, then you won't have to go back and do it again! An easy way to remember this is: Please, Excuse, My, Dear, Aunt, Sally.

Math is full of systems and formulas, and if you follow them correctly, then you will always come out with the right answer.

Leanne

One thing I learned is that instead of thinking of it as please excuse my dear aunt Sally, just think of it as PEMDAS.

If you have all addition or all multiplication in a equation, then you don't need to follow a pattern to figure it out.

Leanne

Do the steps right or you will come up with a way different answer then the right one

Check your problem over and make sure you did all the order of operations right

When you have addition and subtraction you start from left to right. The order of operations makes it simpler to do math.

There are system for lots of thing like math for your benefit.

Order of Operations

Parentheses

exponents

Multiply or Divide

Add or Subtract

The Parentheses are the priority in orders of operations

Learning the Order of Operations will give you solid ground for the rest of mathematics.

Order of Operations is a System if you learn it you will become more efficient at math

Always go left to right but still stay with the priority list

If everybody doesn't have the same agreement for a system it doesn't work

Here is an example of a problem: 16 divided 4 x 2. The order of operations is PEMDAS. So in this problem we can just go left to right, Because multiplication and division are at the same level!

Ruby

Everything you do in math is based on you having a foundation in the order of operations.

Beth

An easy way to remember the order of operations is,

Please/Parentheses

Excuse/Exponents

My Dear/Multiply/Divide

Aunt Sally/Add/Subtract

Great start everyone on your comments. Sometimes it's the obvious steps that we tend to skip over which causes problems down the road. Be sure to check all your steps.

Nice to hear from you Juanita! We'll be glad to have you back in class with us.

There are systems for everything, whether it is making you bed, haltal, leaving the big building after school, and in this case, math.

You have to know all the rules in math, like the order of operations, in order to break them and do them a different way.

I would suggest memorizing these rules over and over again so that you will not forget them.

Michael

Everything else you do in mathematics is going to be based on order of operations

Joe

Order of operations is an easy way to make a hard-looking problem easy

Joe

If you do the problem right and follow the order then you won't get it wrong.

Davis

It is a common mistake if you get the problem wrong or miss a step then you are not doing it right. That is why we check our work.
