Excel is one of the most useful programs and can provide us a wide range of tools to work with data.
In this chapter, you will learn how to use formulas in Excel.
TYPES OF DATA IN EXCEL
In Excel, there are three different types of data that you can enter in a spreadsheet. These are:
Labels: A label is an important entry in Excel. The label is used to define
the information on the spreadsheet, i.e., headings of columns, titles
and names. It is any text besides phone numbers, numbers, formulas,
etc. We do not do any mathematical calculations on labels. Labels are
aligned to the left side of a cell.
Values or Numbers: Values are numeric data on which mathematical calculations are performed.
This type of data includes characters 0–9. The numbers are always aligned to the right side of
the cell.
Formula: A formula is a mathematical expression used to do simple and complex calculations of
the numeric data inserted in a cell or a range of cells. A formula always begins with an equal (=) sign
e.g. = A2 + B2.
