Do maths like a normal person
This is an application where you do calculations "like a normal
person". It lets you type whatever you want, smartly figures out what
computations are needed, and outputs an answer on the right pane.
Then you can plug those answers in to future equations and if that
answer changes, so does the equations it is used in.
