Hello @TheJason,That's a common argument by people. I mean, aside from being in some job that demands it (engineering, math/science teaching etc.), it seems pointless.
Actually, quite a number of useful formulas use algebra. For instance, let's say you needed to calculate interest (bank account).Algebra is very important not only in engineering, Math or Science teaching but also to people who had graduated to a course that does not really need Algebra.
Find the Missing Thing would be a title.First of all let me just define the word "Algebra", a study of mathematical symbols and the rules to manipulate this symbols. Symbols or equations are typically broken or always has a missing link (in layman's terms) so in addition Algebra is also defined as "Reunion of Broken Parts".
