This is an advanced topics course in model theory whose main theme is simple theories. We treat simple theories in the framework of compact abstract theories, which is more general than that of first order theories. We cover the basic properties of independence (i.e., non-dividing) in simple theories, the characterization of simple theories by the existence of a notion of independence, and hyperimaginary canonical bases.

In this seminar you will learn how to simplify square roots whose …
In this seminar you will learn how to simplify square roots whose radicands contain factors that are perfect squares. You will learn how to perform these operations on both integers and variables. You will be able to do this by learning how to identify factors that are perfect squares. These will be necessary skills as you continue to perform operations that contain radical expressions.

The typical system of equations or inequalities problem gives the system and asks for the graph of the solution. This task turns the problem around. It gives a solution set and asks for the system that corresponds to it. The purpose of this task is to give students a chance to go beyond the typical problem and make the connections between points in the coordinate plane and solutions to inequalities and equations. Students have to focus on what the graph is showing.

Represent inequalities on a number line. Represent inequalities using interval notation. Use the addition and multiplication properties to solve algebraic inequalities and express their solutions graphically and with interval notation. Solve inequalities that contain absolute values. Combine properties of inequalities to isolate variables, solve algebraic inequalities, and express their solutions graphically. Simplify and solve algebraic inequalities using the distributive property to clear parentheses and fractions.

This lesson unit is intended to help teachers assess how well students are able to: solve linear equations in one variable with rational number coefficients; collect like terms; expand expressions using the distributive property; and categorize linear equations in one variable as having one, none, or infinitely many solutions. It also aims to encourage discussion on some common misconceptions about algebra.

In this seminar will learn how to use the Quadratic Formula to solve quadratic equations. You will learn to place quadratic equations into the appropriate form in order to use the formula, and you will be shown how to correctly interpret the structure of the formula so that all of the calculations are performed correctly. You will have to apply correct and careful order of operations in order to correctly simplify the radicals. You will apply techniques you have learned to simplify radical expressions. You will then interpret your solutions not only as solutions to the equation, but then translate that information to understand how it relates to the graph of the parabola that represents the function.StandardsCC.2.2.HS.C.5Construct and compare linear, quadratic, and exponential models to solve problems.
