I see that my original strap line "SofAR so good" has been hijacked by the furniture business - "Sofa so good". Better then that I now use the phrase, SofAR for Mathematics, to describe what I do. It also expresses my support for the subject in all its guises.
Originally SofAR was the name I conjured up for my private business, Software by AR (my first and last initials). Now that my private business is primarily Mathematics tutoring I need to think up another interpretation of the mnemonic. Any ideas? Solutions from AR?
