I am trying to learn how to do Orders of Operations and I am having a hard time understanding how to do them properly and get the correct answer.
Here's one of my problems :
21 divided by 7 + 4 x 3
And then there are problems like
5 ( 3+6 ) -3 to the 2 power. I know with the 3 to the second power you times 3 twice. However, that does - before 3 mean? Does this mean - subtracted?
Could someone explain it to me so I can understand it. The directions I have I am having a hard time understanding. Here's what they are :
Step 1 : Do Operations within the Parentheses
Step 2 : Do Operations with Powers and Roos ( What is that ) ?
Step 3 : Do all multiplication and subtraction operations from left to right
Step 4 : Do all addition and subtraction operations from left to right
It's pretty much explanitory to some, however I don't think so. How do you get the answers to the problems?
