Get the kids started on pre algebra problems and monitor their progress. With regular practice, kids will soon be able comfortable solving any kind of algebraic equation! Algebra Problems Looking for algebra problems to give kids to solve? However, some equations, with a proper substitution can be turned into a quadratic equation.

These types of equations are called quadratic in form. In this section we will solve this type of equation. Equations with Radicals — In this section we will discuss how to solve equations with square roots in them. As we will see we will need to be very careful with the potential solutions we get as the process used in solving these equations can lead to values that are not, in fact, solutions to the equation.

Linear Inequalities — In this section we will start solving inequalities. We will concentrate on solving linear inequalities in this section both single and double inequalities. We will also introduce interval notation.

Polynomial Inequalities — In this section we will continue solving inequalities. However, in this section we move away from linear inequalities and move on to solving inequalities that involve polynomials of degree at least 2.

Rational Inequalities — We continue solving inequalities in this section. Absolute Value Equations — In this section we will give a geometric as well as a mathematical definition of absolute value. We will then proceed to solve equations that involve an absolute value. We will also work an example that involved two absolute values. Absolute Value Inequalities — In this final section of the Solving chapter we will solve inequalities that involve absolute value.

Graphing — In this section we will introduce the Cartesian or Rectangular coordinate system. We will illustrate these concepts with a couple of quick examples Lines — In this section we will discuss graphing lines. We will introduce the concept of slope and discuss how to find it from two points on the line. In addition, we will introduce the standard form of the line as well as the point-slope form and slope-intercept form of the line. We will finish off the section with a discussion on parallel and perpendicular lines.

Circles — In this section we discuss graphing circles. We introduce the standard form of the circle and show how to use completing the square to put an equation of a circle into standard form. The Definition of a Function — In this section we will formally define relations and functions. We introduce function notation and work several examples illustrating how it works.

We also define the domain and range of a function. In addition, we introduce piecewise functions in this section. Graphing Functions — In this section we discuss graphing functions including several examples of graphing piecewise functions.

Combining functions — In this section we will discuss how to add, subtract, multiply and divide functions. In addition, we introduce the concept of function composition. Inverse Functions — In this section we define one-to-one and inverse functions. We also discuss a process we can use to find an inverse function and verify that the function we get from this process is, in fact, an inverse function.

Parabolas — In this section we will be graphing parabolas. We introduce the vertex and axis of symmetry for a parabola and give a process for graphing parabolas. Ellipses — In this section we will graph ellipses. We introduce the standard form of an ellipse and how to use it to quickly graph an ellipse.

Hyperbolas — In this section we will graph hyperbolas. We introduce the standard form of a hyperbola and how to use it to quickly graph a hyperbola. ## Main Topics
