Financial Management, Capital Management, Ratios, and the Basics: Assets, Liabilities, & Stockholderĺs Equity



I first bought one of these programs for my college algebra class over 2 years ago and loved it. I do not think I would have passed my class without it. Since then I have bought 10 of these programs and find uses for them everyday in my job. I used the statistics and the business programs for my Six Sigma master certificate 6 months ago. Let me tell you, these programs were a lifesaver as my six sigma black belt project concentrated heavily on statistics. I would highly recommend these programs to anyone who is looking to succeed.


You guys did a great job with this app (I bought "trig made easy" a few years ago, too). It just impresses me how you guys set up something more effectively and straight forward than many other big software companies.
