Excel is a tool that helps you organize and work with numbers, words and pictures. It looks like a big grid with rows and columns inside. Each row is a line of information and each column is a category. For example, if you wanted to make a list of your friends' names, you would have a row with their names, another row that lists their ages, and so on. You can type numbers and words, or even pictures, into the boxes in the grid. You can also do math with the numbers, like adding them together or finding the average. Excel can help keep your information organized and make it easier for you to do math and make charts.
