The If function allows the Spreadsheet to make decisions, based on conditions. 

The If function has the following format: =IF(<Condition> , <True value> , <False value>) 

The Condition is the problem to be evaluated. eg. Amount of wages someone earned to determine their tax bracket. 

The True value is the action to be taken if the given condition is fulfilled. This may be to add a value to something or multiply a value by something etc. 

The False value is the action to be taken if the condition is not fulfilled. 

In any given case, either the False or True actions can be done, as a condition is either True or False, but never both.
