PI is a number that is commonly used to help understand circles in algebra. We all know how it starts out. 3.14.... It is a real and irrational number. Pi is not only irrational. It's much worse. It is trancendental, meaning it is not a root of any polynomial with intefer coefficients. Trancendental numbers are important in algebra, but Pi is studied more in Analysis and Calculus
The whole integer part of the variable X. For example if X = pi, then INT(X) = 3.0
Since "pre-" means before, then pre-algebra would be before algebra. Conversely, algebra would be after pre-algebra. Generally, the next class after a pre-algebra class would be Algebra I, followed by Algebra II.
Pre-algebra preps you for algebra.2nd answer:Pre-AP-algebra is the same as Algebra I. Both are way harder than pre- algebra.

pi = 3.14. It is an important and often used metric dating back hundreds of years in algebra and calculus.
Well I believe that Archimedes measured the Circumference of a circle then divided by the diameter. He then realized through simple algebra that if C/d = pi then d*pi = C
If you use pi as 3.14, the answer is 12.56. If you use the pi button on your calculator, it is still simplified to 12.56, but if you want the full number, it is 12.56637061. The algebra is pi multiplied by diameter OR pi multiplied by radius squared Pi is often just used as 3.14
He estimated pi to 5 decimal places. This estimate was mentioned in Al-Khwarizmi's book on algebra and through that route the estimate arrived in Europe.
Pi is the equivalent of any circle's circumference (the length around the edge of the circle) divided by the same circle's diameter (the length of the line that runs directly through the center of the circle). Pi is always equal to about 3.14.
Pi is a number defined as the ratio of the circumference to the diameter of a circle. many simplify it as 3.14, however, pi is an irrational number, so unless the number is specified in the directions or by the instructor, keep pi as its symbol similar to using an "x" in algebra
The whole integer part of the variable X. For example if X = pi, then INT(X) = 3.0
Circumference = (2) x (pi) x (the radius)Algebra: c=2πr
If you're talking about a rectangle, it's L times W. For the area of a circle, it's r squared times pi.
Pie is 3.14 etc etc etc. Its used in all the formulas to calculate the sums of a circle. Including Diameters, Radiuses and arcs & etc.
Pi is equal to 3.1425. . . . so in Algebra and math we just use the first three digits: 3.14 you just round it. That is the commonly used number even on calculators but be careful the calculator rounds it anyway on your answer usually up!!
