Some of you probably know about the graphic calculators from Texas Instruments.
Although some of them just got released few years ago they are still pretty expensive and not very good in terms of performance.
I had this idea to build my own calculator using a Raspberry Pi.
My question here is what Kind of Raspberry Pi will I need?
Is the Raspberry Pi ZERO enough?
Or should I use one of the newer models because the ZERO can't handle Algebra?
I appreciate all of your help.
