K-12 For Students

The substitution method, commonly introduced to Algebra I students, is a method for solving simultaneous equations. This means the equations have the same variables and, when solved, the variables...

Physics is often seen as a difficult subject; mostly because students don't have a clue where to start when handed an assignment. What flows together so well for the teacher with years of...

Equations that arise in Algebra II include zeros of quadratic formulae, inequalities, absolute value equations and systems of linear equations. There are others, but these provide a solid...

Linear equations are any equation that does not have a term raised to a power greater than one. Linear equations are the first form of equation that a math student will be presented with in an...

Linear equations are the most simple type of algebraic equation. They are called "linear" because, when graphed, the equations take the shape of lines. These equations involve a slope, which is a...

Simultaneous equations use the same variables with different coefficients and constants. There are many ways to solve for the variables in a set of simultaneous equations, including elimination...

Excel Solver is a useful tool for algebra two students, and teaching them how to use it begins with creating columns for equations, constants and solutions. Find out how to execute algebra...

Combining like terms with polynomial equations requires taking terms with the same variable and putting them together. Simplify polynomial equations to solve them with information from a tutor in...

Linear equations are studied in depth in introductory algebra courses. Students will go on to use them extensively to develop more advanced concepts in other high school mathematics and science...

Math problem solving is a skill that is difficult for many students to master. It takes practice, and students often get discouraged when they can't quickly find a solution to a problem. Math...

Linear systems are groups of equations with x and y variables. These variables correspond to the x-axis and y-axis on a graph. Some systems have three equations. These take a little more work, but...

Linear systems require you to solve for the common x, y coordinate among two or more equations. The term equality means each equation uses an = sign. There are several methods of solving linear...

Solving systems of linear equations is a skill not only taught in basic algebra but also tested on the ACT and SAT exams and even job application tests."Solving a system" is fancy language for...

There are many ways in which you can go about solving a linear system of equations, or a group of equations in which each equation represents a straight line. Find the solution to such a system...

A linear system of equations is a system, or group, of equations in which the graph of each equation would be linear, or a straight line. By solving a linear system of equations you can determine...

Problem solving in mathematics is perhaps one of most difficult skills for students to develop. It takes practice, and many students are easily frustrated when they don't see a solution to a...

With graphs, complex equations, and the many different shapes that can be involved, it is no wonder that math is one of the most dreaded subjects for many students. Let me guide you through one...

Polar equations are math functions given in the form of R= f (θ). To express these functions you use the polar coordinate system. The graph of a polar function R is a curve that consists of points...

Whether you are in middle school, high school or even college, you will quickly learn that knowing how to solving equations is essential to any mathematics class. The majority of applications in...

Geometric solids play a significant part of everyday life. They help us decide if our books fit in our backpack or if the packages we've purchased fit in the car's trunk. Students use geometric...
