Instead of guessing whether we are to call it nine, or seven, or a hundred and twenty, or a thousand and fifty, let us agree to call it x, and let us always remember that x stands for the Unknown. … This method of solving problems by honest confession of one’s ignorance is called Algebra.
The Arabs had some cousins who lived not far off from Arabia and who called themselves Hebrews. A taste for Algebra seems to have run in the family. Three Algebras grew up among the Hebrews. I should think they are the grandest and most useful that ever were heard of or dreamed of on earth.
This course will serve as an introduction to the world of algebra and pre-algebra fundamentals, including strategies for solving word problems.
