Rapid Math Tricks and Tips
Mathematics is a difficult subject for many people. Due to the fact that the concepts being
taught can often be tough to learn at times for most as well. Learning a concept requires the
student to draw upon skills that he/she has already learned in prior grades in order to master the
new skill effectively. To help develop old and new skills successfully, Julius (1992) says that
“this number-power program was designed to put you in command, so that you will
never
have
to be intimidated by numbers again…Your ability to process and store information will grow, as
will your self-esteem” (p.1). Julius introduces many tricks a student can use to help him/her to
compute faster mentally and techniques that require minimum to no pencil and paper to figure
out the answer. “Very often, mental calculations can be performed more quickly than with a
calculator. This is especially true when all you need is an estimate” (p.3).
An algorithm that I found intriguing was trick 7: learning how to rapidly square a number
that ends in 5. With this algorithm, to square a number that ends in 5, “first multiply the tens digit
by the whole number, then attach the number 25 to the end of the product” (Julius, 1992, p.31). If
this algorithm includes a zero at the end of the number, disregard the zero and think only of the
one or two digit number. “For each zero initially disregarded in a squaring in a problem, two
must eventually be affixed to obtain the product” (p.32). This process was very easy to learn and
