Excel 2003
Modify cell data
You can edit data in cells this in several ways:
Basic Formula operators
There are several operators that could be used in formulas.
Entering decimal points automatically
If you need to enter lots of numbers with a fixed number of decimal places, Excel has a useful tool:
How to avoid misleading numbers
Applying a number format to a cell doesn't change the value, but only how the value appears in the
worksheet. Formatting can play a joke with you, e.g., sum of values seems incorrect because Excel displays a
limited number of decimal places and their sum is not equal to the real sum.
Changing moving direction of the cell pointer after entering data
Excel automatically moves the cell pointer to the next cell down when you press the Enter key after
entering data into a cell, but you can change this behaviour to move it up, down, left, right and even stay
on.
Using the formula bar as a calculator
If you simply need to perform a calculation, you can use the Formula bar as a calculator.
Referencing cells outside the worksheet
Formulas can refer to cells in other worksheets-and the worksheets don't even have to be in the same
workbook. Excel uses a special type of notation to handle these types of references.
Shortcut key to switch between relative, absolute and mixed references
You can enter nonrelative references (absolute or mixed) manually by inserting dollar signs in the
appropriate positions, or you can use a handy shortcut - F4 key.
Using Arrows in a Chart
Expressiveness of business graphics sometimes determines the success or failure of the presentation and you
can achieve better perception of the audience by using in charts intuitively obvious representation of data
by arrows.
