Celebrating Pi day!

"Celebrated each year on March 14th (3.14), Pi Day is dedicated to the mathematical constant, Pi. First recognized 30 years ago in 1988 by physicist Larry Shaw, Pi Day observers often celebrate with a slice of their favorite pie in honor of the number’s delicious sounding name.

Notated by the Greek letter “𝛑”, pi represents the ratio between a circle’s circumference (perimeter) to its diameter (distance from side to side passing through the center), and is a fundamental element of many mathematical fields, most significantly Geometry. Though modern mathematicians have calculated more than one TRILLION decimal places beyond the standard “3.14,” pi is an irrational number that continues on to infinity! It’s an important ingredient in the formula for the area of a circle, A=𝛑r²." (Google)

" There are in fact 36 PERMUTATIONS (every possible arrangement, even the arrangements that appear similar). For example, 1,2 and 2,1 are the same COMBINATION, but there are two different PERMUTATIONS using these two numbers."
