Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To ...

Revise solving linear equations for your maths GCSE foundation and higher exams with Bitesize interactive practice quizzes covering feedback and common errors.

A new algebra course guide has been released, featuring dynamic geometry software that transforms complex equations into ...

For decades, a math puzzle has stumped the smartest mathematicians in the world. x 3 +y 3 +z 3 =k, with k being all the numbers from one to 100, is a Diophantine equation that's sometimes known as ...

(Notice that the value of r we found is between 2 and 6, as expected.) As challenging as this reversed goat grazing problem was compared to the initial ones we looked at, mathematicians discovered ...
