DM Division and Multiplication (left-to-right)
AS Addition and Subtraction (left-to-right)
EX :
the way you would solve this is:
1.) 3+3x3+3 - The first step this problem is to see all is used in this equation. You will do this by going through the PEMDAS this means:
P- Parentheses ( or )
E- Exponents/ I can’t show you what it looks like but an example is 5 to the 2 power. This does not mean 5x2. You would do 5x5.
M and D- Multiplication and Division (from left to right). There are multiple signs for Multiplication such as ( x ,. ,*) and Division is ➗ or can be shown as a fraction.
A and S- Addition and Subtraction (from left to right) + and -
You may remember this from Elementary school when you most likely first learned these steps from the phrase “ Please Excuse My Dear Aunt Sally”.
In this equation, there is no parentheses or exponents. You will start with the multiplication part of this equation (3+3x3+3). Once you multiply these two numbers you will end up with:
3+9+3
2.) The second step the this equation is to add the first 3 to the 9 and after you do this you will end up with;
12+3
3.) The last step of this equation is to add the 3 to the 12 once you do this you will have your final answer:
15
When you work this out on a piece of paper it should look like this:
3+3x3+3
3+9+3
12+3
15
Once you get more advance in these type of equations you will look for brackets [ ].
