Math 400AB is a prealgebra course conducted in R404 and R408. Half of the class time is spent in a typical lecture class (R404) and the other half is spent in the Math Resource Center computer lab (R408). If you enjoy working on computers, and prefer extra attention, this may be the class for you.
The Math Resource Center also offers an accelerated math course which combines prealgebra (Math 400AB) with elementary algebra (Math 128AB). This modular class is twice as fast as Math 400AB, and is called Modular Math 400AB/128AB.
