Introduction
Formulas! They seem to be the bane of every beginning
mathematics student who has yet to realize that formulas are
about structure and relationship—and not about memorization.
Granted, formulas have to be memorized; for, it is partly through
memorization that we eventually become ‘unconsciously
competent’: a true master of our skill, practicing it in an almost
effortless, automatic sense. In mathematics, being ‘unconsciously
competent’ means we have mastered the underlying algebraic
language to the same degree that we have mastered our native
tongue. Knowing formulas and understanding the reasoning
behind them propels one towards the road to mathematical
fluency, so essential in our modern high-tech society.
The Handbook of Essential Mathematics contains three
major sections. Section I, “Formulas”, contains most of the
mathematical formulas that a person would expect to encounter
through the second year of college regardless of major. In
addition, there are formulas rarely seen in such compilations,
included as a mathematical treat for the inquisitive. Section I also
includes select mathematical processes, such as the process for
solving a linear equation in one unknown, with a supporting
examples. Section II, “Tables”, includes both ‘pure math’ tables
and physical-science tables, useful in a variety of disciples ranging
from physics to nursing. As in Section I, some tables are included
just to nurture curiosity in a spirit of fun. In Sections I and II, each
formula and table is enumerated for easy referral. Section III,
“Applications in Personal Finance”, is a small textbook within a
book where the language of algebra is applied to that everyday
financial world affecting all of us throughout our lives from birth to
death. Note: The idea of combining mathematics formulas with
financial applications is not original in that my father had a similar
type book as a Purdue engineering student in the early 1930s.
I would like to take this opportunity to thank Mr. Al
Giambrone—Chairman of the Department of Mathematics, Sinclair
Community College, Dayton, Ohio—for providing requiredmemorization
formula lists for 22 Sinclair mathematics courses
from which the formula compilation was partially built.
