 Welcome to Unit 1 of Sailor.org's Spreadsheets course. Keep in mind that Excel is flexible. There are different ways to use the rows, columns and formulas to get to your end goal. One approach might be as good as another, and some will be worse. By the end of this unit, you'll be able to describe the basics of what makes a spreadsheet, define some applications of Excel, and identify the components you need to build a useful project. Creating some basic terminology is a must. Cells, rows, columns, formulas, but as you gain familiarity, you'll find that the best way to learn spreadsheets is to sit down at your computer and enter data. It won't be long before you can whip up a family budget or a quick-cost estimate or invoice for your business. In the next unit, you'll get a chance to build on what you've learned. Saving time and money feels pretty good, doesn't it?
