In this learning activity you'll factor problems using the difference of two perfect squares.

The learner reads directions for finding the slope, intercept, and correlation coefficient for a group of ordered pairs using one of eight different scientific calculators.

In this interactive object, learners examine the properties of equality and use those properties to solve simple equations.

In this learning activity you'll identify and calculate the multiplication of monomials.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

In this learning activity you'll factor an algebraic expression of the form AX(Squared) + BX + C using the FOIL technique.

Learners examine the Karnaugh map for a three-variable system. Several examples are given.

In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?

In this animated object, learners follow a process for simplifying radicals.
