I made this project for math class. I am working on making more variables so it can write more expressions. The x block represents the variable x. If it is red it is -x. If a positive x is on the negative/opposite side it will be -(x) If you have a x on the positive side and a red x on the negative side it will represent x-(x). If you drag a piece into the red it will be deleted. if you drag two pieces of the same type on top of each other it will they will cancel out and they will both be deleted. V3 notes: *Added X^2 piece *Made Variables Buttons *Added clear button *Artwork has been changed V4 notes: *Added Y piece *Made pieces not flip over when crossing the line until the piece has been placed. (You no longer have to choose the opposite of the piece you want on the negative side) * Added C-lock which will turn off the project if to many blocks are created. This is designed to keep people (You know who you are) from making lots of blocks. This feature is in beta and will be removed if it makes problems *Added clear button delay
