P

=**​​​Pi-**=

pi is an irrational number used to find the circumference and area of a circle.

the numbers of pi can be found here to a degree [] the pi songs: [] and [] =fun facts:= Did you know that π is the sixteenth letter in the Greek alphabet?

200,000,000,000 digits have been calculated and it still continues.

I would take a person working on a regular desk calculator, 8 hours a day, without errors, 30,000 years to reach the same calculation as a computer made in only 8 hours.

π, does appear in many other mathematical formulas that have nothing to do with circles.

Did you know that Annette Lamb and Larry Johnson created and founded pi!!! COOL!!!

P is for percent equation. the percent equation is where you take a percent and turn it into a decimal. =__Polygon:__ a polygon is a closed plane figure bounded by straight sides,= names of polygons over 14 can be found here [] http://www.coolmath-games.com/0-shapezoid/index.html

  **PERCENT PROPORTION: ** 

A proportion that finds a percent of a number, like 12 % of 30, or the percent of a part, like "what percent of 30 is 3?"

 Parallel Lines-  Lines that are parallel never cross or touch! Go here for more about parallel lines http://www.homeschoolmath.net/teaching/g/parallel_and_perpendicular.php (The yellow lines on the road never cross and never touch!!!)

power- a number that is described using an exponent. Example 10*10 is like saying 10².

Perimeter- the area around a shape or object .[url=http://www.mathsisfun.com/definitions/perimeter.html]Definition of Perimeter[/url]



Perfect Square- A perfect Square is a Rational number that square root is a whole n​umber.



P is for prime factorization. Prime factorization is when you factor a number down to numbers with exponents. here is an example with the number 84.

Positive Numbers!!!! A Positive Number is any number that is above zero. ex.1,2,3,4,5,6,7,8,9,10...

Proportion: Statement of equality of two or more ratios.

P is for Percent as well. A percent is like a fraction. The denominator would be the invisible one hundred, and the numerator is the number that always appears before the percent sign. *A Percent is always a number out of one hundred.*

Examples: 50% is equal to 50/100 or fifty out of one hundred 20% is equal to 20/100 or twenty out of one hundred.​ Plane A two-dimensional flat surface that extends in all directions and contains at least three noncollinear.
