Up until now I had nothing but high praise for Mathematica - and then they went and blew it in one go. I got an email offering an upgrade to 15.0 (personal home use) and thought, why not. I will tell you why not. My previous version was/is 13.30 and it is a perpetual license. So what is the problem? When I downloaded and paid for version 15.0 it suddenly appears that this is now also a YEARLY SUBSCRIPTION. This IS NOT made clear, up front when you are about to make the purchase, it only appears when you have completed. Needless to say I was more than a little unhappy about this and let Wolfram UK know about it. I have uninstalled Mathematica 15.0 and deleted the download file. I have cancelled further payments and I am now awaiting a full refund. In one foul swoop Mathematica have gone from a product I used to rate highly to a 3rd World outfit trying to pull a fast one in the hope of making a quick buck. This is a brainless approach to business Wolfram and I really thought you would know better. Sadly not.

Wolfram.com abuses the good name of Microsoft to get customers. This is a fraudulous organisation that sends bad languaged email to Microsoft customers. Their email isn’t just bad grammar, it also unveils their bad intents, because the email contains words they were not able to translate from their native language. Microsoft and Interpol have been informed.

Wolfram makes Mathematica software. Mathematica is a computer algebra system (CAS) and much more. It does mathematics symbolically. It can evaluate calculus expressions. It is easier to use than Maxima, which is a good open source CAS. The computations are done in "notebooks" which can have text inserted above the calculations. These notebooks can be saved as *.pdf. Mathematica also does 2d and 3d plots. Mathematica expedites your learning of mathematics by eliminating the tedium of pencil and paper calculations. Those hand calculations can be prone to slippery errors. In short Mathematica allows you to concentrate on the theory of why the mathematics works without being bogged down in the computational details.
