Excel

My experience with Excel was positive. Data collection is interesting to me, so this was kind of cool. Spreadsheets (especially Excel) are definitely a very useful tool for budgeting and mortgages because it is very flexible (for example, it accepts quite a lot of different types of data, from time to currency to fractions) and not very hard to use. It's very easy to calculate a lot of numbers and other formula very fast using excel and very fast to graph.
