3. Formula Box: The bar where the contents of the cell are displayed.
4. Worksheet Tabs: These tabs allow you to switch from one worksheet to another. The standard spreadsheet contains three worksheets.
Cell – a single worksheet division
Header – identities/addresses to column, rows and cells
Column*A,B,…+, Rows*1,2,…+ and Cell [A1]
Cells – headers are in terms of cell position within a column and a row [A1 is a cell within column A and row 1 and A5 is a cell within column A and row 5]
Reference – the act of accessing/using cell addresses especially in formulas and functions
Types of references
a) Single cell – addressing a single cell [i.e. A1]
b) Range of cell – addressing a group of cells [i.e. A1:A5- vertical,A1:F1 -horizontal]
Ways of referencing
a) Relative – in a formulae, reference to cells(s) are based on their position relative to the cell that contain the formulae
b) Absolute – the cell referred to is the same no matter which cell refers to it
Functions and formulas
Function – readymade/ predefined mathematical procedures, built into the program library to perform a series of operations on a specified range of values (i.e. average, sum, if etc. –
Formulae – user defined formulae (i.e. =A1+A2+A3)
