Actually useful Excel (Actually useful books)

This is a book for people who have never used a spreadsheet, but need to use one now.
It will work with any major spreadsheet program, but includes examples for Microsoft Excel® 2013.
I’ve assumed that you’ve used a computer, but that’s about it.
The book shows you everything you need to know to develop a simple business model, including cash flow.
This is a deliberately short book: if you want to know every possible function, button, use or permutation of Excel, buy another book. But read this one first.
