I'm sure you would've heard of the term "algebra" and probably are averse of it. Either way, I want to tell you that algebra is really important in computer science and this course marks the beginning of getting into it.
The topics covered in this mini course teach you the very fundamentals of algebra — including such things as expressions, equations, laws of operations, linear equations, quadratic equations. This is a necessary road that you must walk through before getting into advanced forms of algebra.
