Things You'll Need:
- Caculator

Step 1
You must first learn the order of operations. This tells you that you flow the math from left to right -- the order is addition first, subtraction next, multiply and then divided, unless it's in a () then you will follow the same rules but what ever is in a () will go first.
-
Step 2
When you solve an equation the math problem must always be set to zero, this will allow you to simplify the equation. 3x + 5 = 0 if you have numbers like this: The sum of 4 is greater than the sum of five. Example: 4 +x > 5 +x and then solve the problem.
-
Step 3
When you are factoring two equations you need to remember the F.O.I.L. steps to ensure the answer to the problem. F.O.I.L. is first outer inner last; so problems like: (x -7)(x + 7) will get you x^2 - 49, which is considered a perfect square.
-
Step 4
A perfect square is when the inner and outer numbers of the F.O.I.L concept cancel each other out leaving the middle blank.
-
Step 5
When you are dealing with factoring of an equation you must make sure that the denominators are common and the numerators are factoring material. Common denominators allow you to multiply the product and get a simplified answer.

on 9/25/2009 Hi, those are not the correct order of operations. The correct order of operations are PEMDAS: parethesis, exponents, multiplication, division, addition, subtraction. Just remember; Please excuse my dear Aunt Sally. LOOK IT UP! No wonder so many people struggle with this apperently no one knows what they are doing.
