• Worksheet rows lie horizontally and are numbered from 1 to 1,048,576. • Worksheet columns lie vertically and are labeled

from A to Z. Successive groups of 26 columns are labeled AA to AZ, BA to BZ, etc.• A cell is the intersection of a row and column• A cell address or cell reference names a cell and it is

made up from the column letter and row number. Example Cell A3 • The active cell is the current cell.

Entering DATES

You can enter dates and times in a variety of formats in cells, such as 9/1/2016; 9/1/16; September 1, 2016; or 1-Sep-16. You can also enter times, such as 1:30 PM or 13:30.

Using Auto FillAuto Fill enables you to copy the contents of a cell or cell range to continue a series using the fill handle. The fill handle is the small green square in the bottom right corner of an active cell

8

Adjusting Column WidthTo widen a column to accommodate the longest label or value in a column.

9

Selecting a Cell Range

A range is a group of adjacent or contiguous cell. Two cell addresses separated by a colon ( : ) represents a range. Example: C3:D7To select a range, drag from the upper left cell to the lower right cell.

10

Moving a Range

The shortcut key combination for cutting is Ctrl + X and pasting is Ctrl + V.

11

Copying a Range

The shortcut key combination for copying is Ctrl + C and for Paste is Ctrl + V.

12

Merge and center labelsA range of cells can be merged together to become one cell.

13

WRAP TEXT

WRAP TEXT : This button wraps extra long text into multiple lines so we can see all of it without changing the cell width.

Numeric Formats

15

Entering FormulasFormulas are combinations of cell addresses, math operations, values and/or functionsA formula begins with the equal sign (=)

Examples:=A1+A2=C2*5

16

Mathematical Symbols

Operation Common Symbol Symbol in ExcelAddition + +Subtraction - -Multiplication X *Division ÷ /Exponentiation ^ ^

The formula is displayed in the Formula Bar when the cell is selected.The following table shows what mathematical keys to use when entering formulas in Excel.

Example : =C4/D4

Function Basics• An Excel function is a predefined formula that performs a calculation.• A function begins with the equal sign (=) followed by the function name and arguments in parentheses.

Example: =SUM(A1:A3)

18

Basic Functions• Common functions include:

1) AVERAGE arithmetic mean2) MIN minimum value3) MAX maximum value4) COUNT number of values in range5) SUM calculates a total 6) IF logical function

19

The IF Function• It is a function that is used to test the values in a cell and return one value if true and another if false.• The IF function has three arguments:

• A condition that is tested to determine if it is either true or false• The resulting value if the condition is true• The resulting value if the condition is false

=IF(logical_test, “value_if_true”, “value_if_false”)

20

Designing the Logical Test• The logical test is built from the logical operators.

21

Error Meaning#DIV/0! Trying to divide by 0#NAME? Text in the formula is not recognized

#VALUE! The wrong type of operand or function argument is used

####### The column is not wide enough to display the content
