How to apply the Order of Operations (For those of you who don't know that already).

In order to apply the Order of Operations, we have to follow a set of rules called the pemdas that stands for exactly what you need to do in order to solve you equation. Pemdas stands for Parentheses, exponents, multiplication, division, addition, and subtraction. It means you have to do it in this order in order for it to count as a correct answer.

For example:

2 x 3 + (2 - 1)+ 4/2.

     First you have to solve first in the parentheses. 2-1 equals 1 It means you equation now is 2 x 3 +1+ 4/2. Now you do the multiplication. 2 x 3 is 6. Now you rewrite you equation substituting for the 2 x 3. Now your equation is 6 + 1 + 4/2. Now you do do division. 4 divided by 2 is 2. Again, you substitute. Your new equation is now 6 + 1 + 2. Now you must add or subtract from left to the right. In this case it is addition. 6 + 1 is 7, + 2 is 9.

Final Answer: 9
