A spreadsheet is a configuration of rows and columns. Rows are horizontal vectors while columns are vertical vectors. A spreadsheet is also known as a worksheet. It is used to record, calculate and compare numerical or financial data. Each value can either be an independent (i.e. basic) value or it may be derived on the basis of values of other variables. The derived value is the outcome of an arithmetic expression and/or a function (i.e. a formula). Spreadsheet application (sometimes referred to simply as spreadsheet) is a computer program that allows us to add (i.e. enter) and process data.
