No. I was plugging in crazy combinations of r, theta, x, y, z, t, and anything else shown in the built-in demo of that old Mac 3D graphing calculator app years before my teachers got to explaining coordinate systems. I had no idea what most of it meant, but I could make cool looking animated graphics as a third grader…
Also, I found GameMaker which introduced me to using X to the right and Y down in 2D (with the origin in the top-left corner) before algebra was taught to me in school…
