Doing the Math - JHU Mathematics - Johns Hopkins University

absolute value; evaluations; grouping symbols; combining like terms; linear
equations in one and two variables; literal equations; laws of exponents; scientific
notation; graphs of linear equations in two variables; and finding equations of a
line given slope and y-intercept, slope and a point, or two points. A discussion of
slopes of parallel and perpendicular lines is presented. Operations on
polynomials, factoring, and solutions to quadratic equations by factoring are also
covered. Word problems and the use of calculators to solve them are stressed
throughout the course.
Math 82
MAT 82 meets for four contact hours per week, and counts as four billable hours.
However it is a 0 credit course. It does not count toward graduation. MAT 82
covers operations on algebraic expressions; variation; rational equations;
irrational equations; solutions to quadratic equations by completing the square,
by the square root property, and by the quadratic formula; and solutions of
quadratic inequalities. Absolute value equations and inequalities and finding
equations of straight lines meeting specific criteria are emphasized. Graphs of
linear inequalities in two variables, of linear inequalities on one variable, and of
parabolas are also included. Functions and real-world applications of them are
emphasized throughout the course.
Currently, the texts are a sequence of books by the same author. Students who place
into one of these courses are required to complete the full sequence as a prerequisite
to taking a first course for credit. The students have access to a “Math Lab” for help.
They can obtain help in the “Math Lab” from other students and faculty.
For-Credit Courses
There are many for-credit courses available to students to satisfy general college math
requirements. However, most students would like to take either MAT 128 (College
Algebra/Precalculus) or MAT 107 (Statistics) in order to fulfill requirements for their
major. The Math 107 course is a goal for many of the students because it is required
for most of the health-related majors, and this is a large component of the student
body at BCCC. Course descriptions from the course catalog are as follows:
MAT 107: Modern Elementary Statistics (three credits)
Meets Category IV General Education Requirements
45 lecture hours
Prerequisites: MAT 82; ENG 82 (For ESL: ELI 82W) or appropriate
ACCUPLACER scores
Modern statistical methods with applications to the social and natural sciences
are studied. The course focuses on descriptive statistics; probability; probability
distributions; and estimation of statistical parameters from samples, hypothesis
