IS OPERATING IN THE CORRECT ORDER REALLY THAT IMPORTANT?

Does a doctor need to operate in a particular order?
Is there a correct order for getting ready for school?
Is it easier to count when you start with 1?
Is it better to do classwork and practice skills before you take the test?
Is it safer to know how to drive before you go on a road trip?
Is it better to start reading at the beginning of the book?

YES!!!!!

There is a PARTICULAR order we should do things for almost every activity we do in life. In math there is a particular order that we have to work problems. This is called the ORDER OF OPERATIONS, there is an order that we have to work out math problems especially when there are multiple operations used in 1 problem.

Check this out!!! With this problem, 9 + (2 x 4) - 22 ÷ 4, I bet some of you would get 10 and some of you would get 16. Which is correct?

Look at the following stuff to see if it helps you decide










PARENTHESES

EXPONENTS

25 + 6 - 8

31 - 8



ANSWERS: 1.) 24, 2.) 17, 3.) 365

























So what is the answer to 9 + (2 x 4) - 22 ÷ 4? Is it 10 or 16?
