Chemistry is often considered to be a “complicated” subject that is “only for smart people”. Studying Chemistry indeed requires the interest, commitment and practice, however we here at The Zen of Chemistry believe that ANYONE can learn chemistry, given the right tools.
In chemistry one needs to be able to use equations and calculate answers, and in order to do this, being able to rearrange equations to find the desired value is a key skill. Rearranging equations comes easily to those with a strong maths/algebra background, however for some of us, our creative and visual brains just don't work that way, and we need different tools to get the job done.
We're here to tell you THERE IS AN EASIER WAY!

Enter the Equation Triangle
Disclaimer: We do not claim to have come up with this concept, but rather wish to spread its' use for those who find rearranging equations difficult.
The answer to all of your equation rearrangement troubles!
How to use the equation triangle
And now you can apply this idea to every single one of your equation triangles:
Other equation shapes for equations with more than 3 variables
If you wish to determine n, R or T, you would use the top trapezium, as these variables are on the bottom.
If you wish to determine P or V, you would use the bottom trapezium.
The five equations derived from this trapezii are:
The same goes for equation squares and other equations:
