Spreadsheet is ok it is useful. You can do a lot of different things with a spreadsheet, and most of the work it does for you which makes it way easier. I am planning on using spreadsheet in my class foralot of different reasons but the main reason is for keeping my grades in line. Once i have it all togther then it does all the work for me which will take a big load of my back.As teachers we use spreadsheets because it is easier to keep everything organized while not using a ton of paper. There is a huge advantage of using spreadsheet over a calculator, spreadsheet all you have to do is enter the equation first then after that all you do is enter the numbers and it does all the calculations by it self.I think the three primary functions, which are storing, calculating, and presenting information. I think these are the best reasons to use spreadsheet, and i will not be using it for anything else
