MATH CALCULATION is a broad term that encompasses many different types of calculations. NORM, SLOPE, AREA, MODE, and SUM are all specific types of math calculations. NORM stands for normalization, which is the process of adjusting values to a common scale. SLOPE is the rate of change between two points on a line. AREA is the measure of the size of a surface or region. MODE is the most frequently occurring value in a set of data. Finally, SUM is the total of two or more numbers added together.
