To fully utilize the features in the worksheet, you must have a OneDrive account. OneDrive is a way to store your files online. This is often referred to as storing files in the cloud. When you store a file online, you can access it from anywhere using a variety of devices including a laptop computer, a desktop computer, a mobile phone, or a tablet PC.
You may already have an account. One drive is part of Windows Live. If you have any type of Windows Live account, such as Hotmail or Xbox Live you have a OneDrive account. If you do not have an account, you can sign up for one free. Go to http://onedrive.live.com to sign up.
OneDrive gives you access to the Excel web app. The Excel web app is a mini Excel. You can use it to create and modify Excel files. When using this tutorial, you can use it to practice the concepts taught. The web app does not have all the features of Excel, but it does have all the key features, and, for the most part, they work the same way as they do in Excel.
