1. What are two common uses of Excel in the workplace?

2. Why do you think Excel is considered a powerful tool for analysing data?

Excel is a powerful tool that helps you organise, analyse and present data. In this chapter, you
will learn how to use formulas, create charts and manage information to make tasks easier and
more efficient.

USING FORMULAS TO PERFORM CALCULATION

In mathematics, formulas help with calculations and Excel works the same way. Formulas in Excel

start with an equal to (=) sign. If you forget the equal sign, Excel will consider the data as text and
the calculations won’t work.

ELEMENTS OF A FORMULA
The elements of a formula are:

References: These are cell addresses or ranges of cells
used in calculations (e.g., A1, B2:C5).

Operators: These symbols indicate the operation The maximum length of a formula
to perform, such as addition (+), subtraction (-), in Excel is 8,192 characters.
multiplication (*) and division (/).

Constants: These are fixed values, like numbers (5, 10) or text (Hello), that remain unchanged
during calculations.

DIFFERENT WAYS TO ENTER FORMULAS
You can enter the formula directly into the cell or through the formula bar.

Enter a formula directly into the cell: You can type the
formula directly into the cell by starting with an equal sign
(=B2*C2) and then press the Enter key to see the result in the
cell D2.

Enter a formula in the formula bar: Select the cell and
enter the formula in the formula bar (=B2*C2), then press
the Enter key to see the result in the cell D2.
