Disclaimer: I'm brand new to this calculator as well as the TI family. My tech experience is nothing beyond playing with Android.

Moving on. So I'm trying to figure out how to make a program that will solve for Ohm's law. Something that would allow me to input any 2 of the 4 values and solve for the 2 that I did not input. In case you're not familiar with Ohm's law here it is

P= E*I R=E/I E=√P*R I=√P/R

P=I^2*R R=E^2/P E=P/I I=P/E

P=E^2/R R=P/I^2 E=I*R I=E/R

I would like the program to just list P,R,E,I and allow me to input any two of those. I tried to achieve this in the spreadsheet app with no success. Any help guiding me through this would be greatly appreciated. I will post the finished product for others to utilize.

Thanks
