In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."
The Regular Square Pyramid
By Allen Reed, Douglas Jensen
Learners study the properties of a regular square pyramid and use geometric formulas to find volume and surface area.
The Mathematics of Buying: Putting It All Together
By Mary Lee Rudnick-Kaun
Learners tackle this interactive learning object after studying the mathematics of buying. This activity ties together the ideas of net cost, list price, trade discounts, cash discounts, net cost equivalent, and single discount equivalent, as well as the concepts of part, base, and rate.
In this interactive object, learners study the properties of a trapezoid and use a geometric formula to find its perimeter and area.
Simplifying Algebraic Expressions: Multiplication
Learners read definitions of the terminology associated with algebraic operations and then follow steps to use the fundamental laws of multiplication to simplify algebraic expressions.
