Solving 6 math problems using different methods is the idea behind this video. First, you make three rows of numbers vertically from 1-9. All the numbers match across for example, 1 1 1, 2 2 2, 3 3 3, and so on. Each set of numbers creates a mathematical problem who's solution is the number six. These problems require some thinking to solve. The only one that is immediately apparent is 2 2 2=6 which is, of course, 2+2+2=6, (3x3)-3=6, the square root of 4 =2. This done on all three of the four...

Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line. Similarly a solution of a system of equations is points that satisfy each and every equation of that system. A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...
A method for solving a linear system with no solution is described. The method is described in 4 steps.

In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...
