Finding methods to quickly and accurately solve simultaneous equations is an age-old mathematical problem. A classic algorithm for solving linear systems, dubbed Gaussian elimination in modern ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

One of the most common methods used to solve equations is the balance method. Imagine an equation as a set of scales. The scales will stay in balance as long as the same operation (addition ...

The equation contains a set of brackets. The easiest way to solve equations with brackets is to expand the brackets. \(\text{Area of a rectangle} = \text{base} \times \text{height}\). This means ...
