## Week 2 - Working with Formulas and Functions (Ch2)

### Overview

With its capabilities in mathematical, scientific, engineering, and other calculations, Excel is a valuable tool for business, government, education, and you. You can use Excel to create a simple addition formula or a sophisticated calculation with layers of arithmetic. In this chapter, you learn how to build a basic formula and how to use mathematical rules. You also explore Excel function categories.

We also take a quick look at the original spreadsheet software, VisiCalc. Some even consider this the first "killer app" before that was even a known term.

### Objectives

- Build and edit basic formulas.
