I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

comment Getting unwanted solution from Solve
Formally, solution 4 is just as valid as solution 3. I see no problem with the results Solve is returning.

comment Non sequitur in documentation of MemberQ
You may be right, but I'm not convinced. To me there is no context in this sentence to establish any relation at all between MemberQ and Element. And, since the sentence stands alone, no other context to establish a relationship, either.

comment Importing multiple files with a loop
Just for starters, Data[[20.1]] is invalid syntax, list indices must be integers.
