Read the Documentation Read the SPME User Guide DOWNLOAD HERE Testimonials: "I have both SPME and Equation Solver and, to me, are some of the most useful software I have ever owned. I am an owner of a marketing consulting firm and work with two universities and their MBA programs (Quant. Analysis and Statistics courses for Marketing executives) and the software is easier to use and more intuitive than Excel. In addition, the support is industry leading. I have inquired many times for help and the step by step problem solving that was provided is a value add that exceeds the costs of the programs by many times. Support like that in today's world is unheard of. It is as though they wrote the software for me. I intend to purchase Accounting Finance Business Made Easy in the next few weeks." Steve P, Director, SBP Group 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. V. S. Worth every penny!!! Two years ago I purchased the 5 app special and Im still discovering new capabilities on a regular basis. A must have for every student and professional. I am still amazed by how much time and thought the designers invested in these programs. I can honestly say they did a great job and they stand by their product. Customer service/technical help is impressive too!!
