Permutations are easy to understand...but take time to get to why we work them out the way we do so you can understand them better. This video also looks at how permutations differ from combinations, and well as looking at simple permutations, permutations with limited spaces, permutations with repeats, and permutations in a circle.

Solve simultaneous equations using the elimination method.
The steps are as follows:
The Elimination Method
Step 1: Multiply each equation by a number so that the two equations have the same coefficient for a selected variable.
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation to get the value of your first variable.
Step 4: Substitute into either Equation 1 or Equation 2 above and solve for the second variable.

Linear equations from graphs. Like it sounds, we will use the graphs of linear equations to produce the equation itself, using the slope intercept method (y = mx + b). Using this method we will first determine the y intercept, and then the gradient of the equation.
This is part of a series of videos looking at linear equations.
