pi 3.14
I = interest, P = principal, r = rate, and t = time
Mean: The mean is equal to the total of the values of a data set,
divided by the number of elements in the data set.
Median: Median is the middle value in an odd number of ordered
values of a data set, or the mean of the two middle values in an even
number of ordered values in a data set
