Some people have a hard remembering the milloins of formulas that Mathmatitions use on the daily. Well I decided to create a webpage that has all of the most common Formulas the to easily forgotten. I don't know how other people learn in school, but I learn best when given the information, memorize it then after the tests with that topic on it, I forget it. SO I thought it would be nice to have all of this information in a place for everyone to look for the information they need. I hope this is useful to any readers and thank you for reading. Here is a table of the equations for grades 6th through 11th.The formulas that will be shown are...

- Perimeter
- Circumference
- Area
- Surface Area
- Volume
- Pythagorus Theorem
- Distance Formula
- Slope of a line
- Midpoint Formula
- Quadratic Formula

Color! | Why? | Easy way to remember it |
---|---|---|

Bright Pink | Very difficult to remember | Say the equation in the rythm of the song Row Row your boat |

Dark-ish Green | Has many forms | Write each form then resite it, if you get it wrong repeat this process |

Navy Blue | Not very difficult for anyone to remember, although if you do have trouble it is A-Okay | Recite the equation until you think you have memorized it |

Name of Equation | Equation | Variables |
---|---|---|

Perimeter | P=4A P=2(l+b) |
