Data in Worksheet Three types of data can be entered, numbers/characters (012345678 + – (), 1 $; %, E, e), text and formulas.

Formula -Formula is a sequence of values, cell address, names functions or operators in a cell that produces a new value from existing values.
Cell Referencing Each cell in worksheet has a unique address, when cell address is referred in formulas, it is called cell referencing.

Relative Referencing Cell referencing in which the cells are referred by their relative position in the worksheet relative to a particular cell.

Absolute referencing The cell referencing in which the cells are referred by their fixed position (absolute position) in the worksheet.

Mixed Referencing Combination of relative and absolute referencing is called mixed referencing.

Functions Functions are predefined formulas that perform calculations by using specific values, called arguments.

Arguments Arguments are the-values passed to the functions, using which the function carries out some task. It can be numbers, text, logical values, constants, formulas or other functions.
