For example, the SUM function adds values in a range of cells. A formula with a function has three parts: an equal sign, a function name, and at least one argument. The equal sign identifies the cell contents as a formula. The function name identifies the operation to be performed. The argument is the value the function uses to perform a calculation, including a number, text, or a cell reference that acts as an operand. The argument follows the function name and is enclosed in parentheses. If a function contains more than one argument, commas separate the arguments.

Second, select the function you want to use. Third, enter the arguments. Finally, enter the completed formula. The results appear in the cell. The best way to select a function is from the Insert Function dialog box. Click the Insert Function button on the Formula Bar to open the Insert Function dialog box. You can also enter a formula with a function directly in a cell by typing an equal sign, the function name, and the argument. Formula AutoComplete helps you enter a formula with a valid function name and arguments.

Some mathematical operations, such as addition, subtraction, multiplication, and division, do not require functions. Mathematical and trigonometric functions are particularly useful when you need to determine values such as logarithms, factorials, sines, cosines, tangents, and absolute values. You used a mathematical and trigonometric function when you created a formula with the SUM function.

For example, statistical functions can determine the average, standard deviation, or variance of a range of data. Statistical functions can also determine the number of values in a range, the largest value in a, range, and the smallest value in a range. Examples are AVERAGE, MIN, and MAX. Financial functions: Financial functions are used to analyze loans and investments. The primary financial functions are future value, present value, and payment.

In the IF function, the first argument sets a condition for comparison, called a logical test. The second argument determines the value that appears in the cell if the logical test is true. The third argument determines the value that appears in the cell if the logical test is false.

For example, date and time functions can be used to convert serial numbers to a month, a day, or a year. A date function can also be used to insert the current date or the current date and time. Text functions: Text functions are used to format and work with cell contents. A text function can be used to convert text in a cell to all uppercase or lowercase letters. Text functions can also be used to repeat data contained in another cell.
