12/3/2007 Pre Algebra - Zero & Negative Exponents

Today we introduced the rules for zero and negative exponents. Simply put, negative exponents change places in the fraction and become positive, for example three to the negative 2nd power on the top becomes three to the positive second power on the bottom. Also, any number or expression to the zero power becomes 1.

12/3/2007 Applied Geometry - Conditions for Parallelograms

We will continue our work with parallelograms today, using the six conditions for parallelograms (the 5 from last week and a new one, if one pair of sides are both parallel and congruent) to decide if a given quadrilateral is a parallelogram. It will serve as a good review of the properties of parallelograms as well as some more algebra, setting up equations and solving.
