Math Review Workbook
Unfortunately, math is often the most
disliked and least understood subject taught in school. This usually
results from a failure, either on the part of the teacher or student,
to appreciate the practical usefulness of math. Problems are considered
merely as "numbers," and the student never really knows how
this information was obtained and can be used in later life. As a
result, the student sees no good reason why they should attempt to
understand even the most basic operations. What does this have to do
with taking an exam? The answer is this, without understanding basic
math operations, you cannot
hope to pass an exam or be successful in the construction industry.
This book will take you through the many
categories of math questions of which an electrician is required to
have knowledge for the electrical exam. I will repeat categories in
exams through out the book.
You cannot excel in a subject if you
don't understand it. The key is learning and understanding a subject.
Memory comes from overlearning. You don't forget how to walk or ride a
bicycle. Too many try to cram for a test or to memorize answers from
previous exams. This results in failure.
For some electricians, it has been
twenty years or more since they have used math formulas. For most, the
last time was an apprenticeship class. Now, for the exam, we are
required to be an expert in applying all of the formulas.
