Working with Formula
Formulas are the lifeblood of worksheets.Without formula worksheet will be just simple tabular
representation of data. A formula consists of special code which is entered into a cell. It
performs some calculations and returns a result, which is displayed in the cell.
Formulas use a variety of operators and worksheet functions to work with values and text. The
values and text used in formulas can be located in other cells, which makes changing data easy
and gives worksheets their dynamic nature. For example, you can quickly change the data in a
worksheet and formulas works.
Elements of Formulas:
A formula can consist of any of these elements:
• Mathematical operators, such as +(for addition) and *(for multiplication)
Creating Formula:
For creating formula you need to type in Formula Bar.Formula begins with ‘=’ sign. When
building formulas manually, you can either type in the cell addresses or you can point to
them in the worksheet. Using the Pointing method to supply the cell addresses for formulas
is often easier and more powerful method of formula building. When you are using built-in
functions, you click the cell or drag through the cell range that you want used when defining
the function’s arguments in the Function Arguments dialog box.See below screenshot.
