A function formula is a special formula that names a function instead of using operators to calculate a result. Excel has more than 400 built-in functions and categorized into: logical, mathematical, statistical, text, date and time, financial, lookup, etc. These functions can be found in the FORMULAS tab under the Function Library section or you can search and apply it using the Insert Function tool.
In this video tutorial, I explained and demonstrated in detailed the use of function formula and give examples to some of the mathematical and statistical functions used in excel such as sum(), product(), quotient(), average(), min(), max(), and count().
