Functions exist for basic mathematical operations such as absolute values, lowest and greatest common denominators, square roots, and sums. Plenty of high-end operations also are available for things such as matrix multiplication, multinomials, and sums of squares. Not all of Excel’s math functions are useful in a business context, but a surprising number of them are. For example, operations such as rounding and generating random numbers have their business uses. ...
