Editing Formula (section)

==In computing==
In [[computing]], a formula typically describes a [[calculation]], such as addition, to be performed on one or more variables. A formula is often implicitly provided in the form of a [[Instruction (computer science)|computer instruction]] such as.

: ''Degrees Celsius'' = (5/9)*(''Degrees Fahrenheit''&nbsp; - 32)

In computer [[spreadsheet]] software, a formula indicating how to compute the value of a [[cell reference|cell]], say ''A3'', could be written as

: ''=A1+A2''

where ''A1'' and ''A2'' refer to other cells (column A, row 1 or 2) within the spreadsheet. This is a shortcut for the "paper" form ''A3 = A1+A2'', where ''A3'' is, by convention, omitted because the result is always stored in the cell itself, making the stating of the name redundant.
