Calculator: trinomial

You can use this calculator if you want to calculate a value using a trinomial. You have a choice of direct and inverse proportion. An example of direct proportion is "if 10 popsicles cost 200 crowns, how much do 20 popsicles cost?", an example of inverse proportion is "if I download a movie at 10 mbps in 200 seconds, how many seconds would it take me to download the movie if I downloaded it at 20 mbps?" More on the theory in a separate article on the triplet.
