Ms Excel functions for calculation

You can use Excel functions to perform mathematical calculations. By using functions, you can quickly and easily make many useful calculations, such as finding an average, the highest number, the lowest number, and a count of the number of items in a list. Microsoft Excel has many functions that you can use.

Using Reference Operators

To use functions, you need to understand reference operators. Reference operators refer to a cell or a group of cells. There are two types of reference operators: range  and union.

A range reference refers to all the cells between and including the reference. A range reference consists of two cell addresses separated by a colon. The reference A1:A3 includes cells A1, A2, and A3. The reference A1:C3 includes cells A1, A2, A3, B1, B2, B3, C1, C2, and C3.

A union reference includes two or more references. A union reference consists of two or more numbers, range references, or cell addresses separated by a comma. The reference A7, B8:B10, C9, 10 refers to cells A7, B8 to B10, C9 and the number 10.

Work with the Insert Function button

• Excel supplies more than 350 functions organized into 10 categories:

  • Database, Date and Time, Engineering, Financial, Information, Logical, Lookup, Math, Text and Data, and Statistical functions

• You can use the Insert Function button on the Formula bar to select from a list of functions.

• A series of dialog boxes will assist you in filling in the arguments of the function and this process also enforces the use of proper syntax.

Understanding Functions

Functions are prewritten formulas. Functions differ from regular formulas in that you supply the value but not the operators, such as +, -, *, or /.

Function Library

The function library is a large group of functions on the Formula Tab of the Ribbon.  These functions include:

AutoSum:  Easily calculates the sum of a range Recently Used:  All recently used functions Financial: Accrued interest, cash flow return rates and additional financial functions Logical: And, If, True, False, etc. Text: Text based functions Date & Time: Functions calculated on date and time Math & Trig:  Mathematical Functions

For example, you can use the SUM function to add. When using a function, remember the following:

• Use an equal sign(=) to begin a formula.

• Specify the function name.

• Enclose arguments within parentheses. Arguments are values on which you want to perform the calculation. For example, arguments specify the numbers or cells you want to add.

• Use a comma to separate arguments.

Here is an example of a function:

=SUM(2,13,A1,B2:C7)

In this function: the equal sign begins the function; SUM is the name of the function; 2, 13, A1, and B2:C7 are the arguments; parentheses enclose the arguments; commas separate the arguments.

After you type the first letter of a function name, the AutoComplete list appears. You can double-click on an item in the AutoComplete list to complete your entry quickly. Excel will complete the function name and enter the first parenthesis.

One or more functions may be specified in a formula to help calculate a desired final value in a cell. The most commonly used functions can be found under the AutoSum button , which looks like a summation symbol in mathematics and found on the Home tab under the Editing.

Creating Excel Functions, Filling Cells.

Exercise 1

Consider the following table of student names and homework scores. The block of cells A1:D5 contain constant values (text and numbers).

To compute the SUM over the column of HW#1 scores in cell B7 perform the following:

1. Click on the cell B7 to make it the active cell.

2. Click the AutoSum button’s drop-down menu and choose Sum.

3. Highlight cells B2 through B5 with your mouse (Excel will outline the cells in the chosen range). The formula shown in cell B7 will be =SUM (B2:B5), where the function called SUM is given the range B2:B5 is its input argument.

4. The cell B7 will display evaluated value (final answer) for the formula.

The AutoSum button contains other commonly used as listed below:

Sum: Add all the numeric values contained in the cells specified in the input argument.

Average: Averages all the numeric values contained in the cells specified in the input argument.

Min: Determines the smallest numeric value among all the cells specified in the input argument.

Max: Determines the largest numeric value among all the cells specified in the input argument.

Count: Counts how many cells contain numeric values in the input argument.
