This generates random expressions that have a decent amount of randomness. You can write them down, assign values to the variables to test people at math, and just to right down expressions. The keys are... q: start the drawing mechanism, this is to be able to write down equations a: stop drawing, when you don't want there to be a blue scribble following you around z: set size to ten space: clear all up/down arrow: The up arrow increases the size of your drawing while the down arrow lowers it right/left arrow: They change the color of your writing, if you change it with one arrow you can go back with the other (if pressed while writing it will not change the board)
I was taught this trick, but added the drawing ability. disclaimer: there are no correct answers because the variables are undecided.
