© Paradigm Publishing, Inc. 5 Write Formulas - continued If a formula contains two or more operators, Excel uses the same order of operations used in algebra. From left to right in a formula, this order, called the order of operations, is: negations (negative number—a number preceded by a minus sign) first, then percents, then exponentiations, followed by multiplications, divisions, additions, and finally subtractions.

10
© Paradigm Publishing, Inc. 10 Write Formulas - continued Excel is a sophisticated program that requires data input and formula creation to follow strict guidelines in order to function properly. When guidelines that specify how data or formulas are entered are not followed, Excel will display one of many error codes. When an error is identified with a code, determining and then fixing the problem is easier than if no information is provided.

12
© Paradigm Publishing, Inc. 12 Insert Formulas with Functions =SUM(B2:B5) is an example of a formula. The beginning section of the formula, =SUM, is called a function, which is a built-in formula. A function operates on what is referred to as an argument. An argument may also contain a constant. When a value calculated by the formula is inserted in a cell, this process is referred to as returning the result.

16
© Paradigm Publishing, Inc. 16 Insert Formulas with Functions - continued Excel performs over 300 functions that are divided into thirteen different categories including Financial, Date & Time, Math & Trig, Statistical, Lookup & Reference, Database, Text, Logical, Information, Engineering, Cube, Compatibility, and Web.

17
© Paradigm Publishing, Inc. 17 Insert Formulas with Functions - continued Excel includes the Formula AutoComplete feature that displays a drop-down list of functions. AutoComplete list

18
© Paradigm Publishing, Inc. 18 Write Formulas with Statistical Functions AVERAGE function The AVERAGE function returns the average (arithmetic mean) of the arguments.

19
© Paradigm Publishing, Inc. 19 Write Formulas with Statistical Functions - continued MIN function The MAX function in a formula returns the largest value in a cell range. The MIN function returns the smallest value in a cell range.

20
© Paradigm Publishing, Inc. 20 Write Formulas with Statistical Functions - continued COUNT function Use the COUNT function to count the number of cells that contain numbers within the list of arguments.

22
© Paradigm Publishing, Inc. 22 Write Formulas with NOW and TODAY Functions Date & Time button The NOW and TODAY functions are part of the Date & Time category of functions. The NOW function returns the current date and time in a date and time format. The TODAY function returns the current date in a date format.

23
© Paradigm Publishing, Inc. 23 Display Formulas In some situations, you may need to display the formulas in a worksheet rather than the results of the formula. Display all formulas in a worksheet, rather than the results, by clicking the FORMULAS tab and then clicking the Show Formulas button in the Formula Auditing group. You can also turn on the display of formulas with the keyboard shortcut Ctrl + `. Press Ctrl + ` to turn off the display of formulas or click the Show Formula button on the FORMULAS tab.

24
© Paradigm Publishing, Inc. 24 Use Absolute and Mixed Cell References A reference identifies a cell or a range of cells in a worksheet and can be relative, absolute, or mixed. A relative cell reference refers to cells relative to a position in a formula. An absolute cell reference refers to cells in a specific location. A mixed cell reference does both: either the column remains absolute and the row is relative or the column is relative and the row remains absolute. Distinguish between relative, absolute, and mixed cell references using the dollar sign ($).

25
© Paradigm Publishing, Inc. 25 Use Absolute and Mixed Cell References - continued absolute cell reference In some situations, you may want a formula to contain an absolute cell reference, which always refers to a cell in a specific location.

26
© Paradigm Publishing, Inc. 26 Use Absolute and Mixed Cell References - continued mixed cell reference In a mixed cell reference, either the column remains absolute and the row is relative or the column is relative and the row is absolute.
