AND function and ways to use
This article describes the formula syntax and usage of the AND function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

Description
Objective: Returns TRUE if all its arguments evaluate to TRUE; returns FALSE if one or more arguments evaluate to FALSE.

One common use for the AND function is to expand the usefulness of other functions that perform logical tests. For example, the IF function performs a logical test and then returns one value if the test evaluates to TRUE and another value if the test evaluates to FALSE. By using the AND function as the logical_test argument of the IF function, you can test many different conditions instead of just one.

Syntax
AND(logical1, [logical2], ...)The AND function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

logical1  Required. The first condition that you want to test that can evaluate to either TRUE or FALSE.
logical2, ...  Optional. Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.
Remarks
The arguments must evaluate to logical values, such as TRUE or FALSE, or the arguments must be arrays (array: Used to build single formulas that produce multiple results or that operate on a group of arguments that are arranged in rows and columns. An array range shares a common formula; an array constant is a group of constants used as an argument.) or references that contain logical values.
If an array or reference argument contains text or empty cells, those values are ignored.
If the specified range contains no logical values, the AND function returns the #VALUE! error value.
