Successful communication of ideas has been and will continue to be a limiting factor in man's endeavors to survive and to better his life. The invention of algebra, essentially a graphic technique for communicating truths with respect to classes of arithmetic statements, broke the bond that slowed the development of mathematics. Whereas "12+ 13=25 '' and "3+7= 10" and "14+(-2) = 12" are arithmetic statements, "a+b=c '' is an algebraic statement. In particular, it is an algebraic statement controlling an entire class of arithmetic statements such as those listed.
