This referred to a particular type of mathematics that was mainly a leisure pursuit for rich men. Algebra has come a long way since then, and the algebra studied today is very far removed from the original kind. For interested mathematicians, or advanced students, algebra becomes a more abstract subject. It involves the study of formal number systems of which the systems we use in everyday life are just examples. Students, and concerned parents subscribe for help with algebra.
Some people just tune in for the occasional challenge to stop their brains seizing up.
As well as this, we regularly discuss teaching methods, other branches of mathematics than algebra, mathematical conventions, numerical methods, prices of calculators, etc. Off-topic discussions are inevitable, but a mainly algebraic theme would be appreciated. Well, don't rely on it. The nice helpful people here would rather spend twenty minutes helping you understand a concept in algebra than 5 minutes doing your work for you. Even if someone does it once or twice, they are providing solutions for you to look through and understand, or answers for you to check your work against.
