Rearranging Formulae
IGCSE 0580
Topic:Algebra and graphs
Core: C2.5
Solve linear equations in one unknown.
Change the subject of simple formulas. (the subject only appears once • there is not a power or root of the subject)
Extended: E2.5
Solve linear equations in one unknown.
Solve fractional equations with numerical and linear algebraic denominators.
Change the subject of formulas. (the subject appears twice • there is a power or root of the subject)
This skill in not limited to only this section of work. It is the basis of algebra and you will need to rearrange formulae in many other topics as well.
Rearranging Formulae - 1
In this video, we will start with some easy equations; in the following videos, the examples will become more difficult. This is probably one of the most important skills you need in Mathematics.

Make X the subject - Part 1
This is a little tricky since we don't only work with numbers, but with variables, but we still follow the same rules. This is probably one of the most important skills you need in Mathematics.
Make X the subject - Part 2
This is a little tricky since we don't only work with numbers, but with variables, but we still follow the same rules. This is probably one of the most important skills you need in Mathematics.
Equations with indices
Just when you thought it couldn't get any worse, they add indices to the equations. Good luck. I hope you're sitting down for this video 🙂
