This is what a competent encyclopedic treatment of algebra looks like by comparison. The other algebra article fucks up from the jump, because the goal of an encyclopedic treatment of algebra is not to teach someone the mechanics of solving a handful of elementary algebra problems (you can as a small aid, but making it nearly the entire article is failing the assignment completely).

It’s to cover what algebra is, its various subfields, its history, its applications, its relationships to other parts of math, etc. Covering algebra encyclopedically by offering a mediocre Algebra I tutorial is like covering internal combustion engines encyclopedically by making the entire article a short guide on how to change the oil in your car; it’s asinine.
