||Conferences & Workshops. Formulas are the heart and soul of a spreadsheet. Without formulas, Excel would be nothing more than a grid for displaying numbers and text. As you will see in this workshop, formulas can do a lot more than just adding, subtracting, multiplying, and dividing. Excel has hundreds of different formulas you can use to create complex statistical, financial, and scientific calculations. In this workshop, you’ll learn about more complex formula writing, how to insert and edit functions, how to define names, and how to trace formulas and diagnose errors.
