While its uses can vary greatly, the structure of the Function itself is very simple, in that it will return either TRUE or FALSE. This is certainly the most important aspect of this Function.

## When to Use IF( )

The IF Function can be used whenever we wish to have the ability to return a particular result that is dependant on another

For example we may want a formula to SUM a range of cells if the value of a particular cell is greater than 100, but if the value of this particular cell is less than 100 we may wish to perform another calculation altogether.

This is often referred to as the What-If analysis: What if this were that value or what if this was another value?

While the IF Function can be used on its own, it is often combined with another Function.

This combining of Functions in Excel is what is known as: Nesting.

### What is Nesting?

#### nesting, in Excel, means using the result of one Function as the argument of another.

For example, we may want a formula to SUM a range of cells if the value of a particular cell is greater than 100, but if the value of this particular cell is less than 100 we may wish to perform another calculation altogether.

This is often referred to as the What-If analysis: What if this were that value or what if this was another value?

### Try this yourself *before *watching the video below

TASK:

If the SUM value of the 10 numbers you input exceeds 100, then return the actual SUM value of the numbers.

If, however, the SUM value does not exceed 100, then return only the MAXIMUM number within the range.
