Microsoft Excel allows users to create, modify and organize a visually appealing and presentable spreadsheet to share with co-workers and clients. While the formulas and functions of Microsoft Excel can be hard to learn and remember, knowing how to input the formulas can save you valuable time on calculations. With simple addition and multiplication formulas and few clicks and drags of the mouse, you can add the total of each column and find the product of the two columns.
Launch the Excel program, and open the spreadsheet you want to modify by left-clicking on the "File" tab and choosing the "Open" option from the drop-down menu. Find and highlight the file, and press "OK" to open.
