What Does It Do ?

It can be used either horizontally or vertically.
The numbers can be in single cells, ranges are from other functions.
Syntax
=SUM(Range1,Range2,Range3... through to Range30).

Note
Many people use the =SUM() function incorrectly.
This example shows how the SUM has been combined with plus + symbols.
The formula is actually doing more work than needed.
It should have been entered as either =C48+C49+C50 or =SUM(C48:C50).
