Basic Formula operators

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.

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.

Creating and using named ranges

Range names is a powerful Excel feature which allows you to give a symbolic name for the cell or range of cells to be later used as convenient replacement for cell/range address in formulas.
