What are Functions?
A function is a ____________________ to write an equation that performs a calculation. For example, the SUM function adds values in a range of cells.
Functions often simplify formulas that are long or complex
Excel includes functions to perform complex calculations in specialized areas of mathematics, including __________, logic, trigonometry, accounting, and finance

5. Microsoft Office 2007: Introductory
What are Functions?
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 _________ to be performed.
The ____________ 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.

6. Entering Formulas with Functions
To enter a formula with a function, first, start the formula with an equal sign. 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 ________ _______________. Click the Insert Function button on the Formula Bar to open the Insert Function dialog box.
First, click a category in the “Or select a category box”, and then click the function you want in the Select a function box. A brief description of the selected function appears near the bottom of the dialog box.

Types of Functions
Mathematical functions and trigonometric functions: These functions manipulate ____________ data in a worksheet.
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 ________ function.

19. Types of Functions (continued)
Logical functions, such as the IF function, display text or values if certain conditions exist. In the IF function, the first argument sets a condition for comparison, called a ______________. 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.
