The image below is "7th Grade math". The question was which image looks closest to the original. Zearn's "Tower of Power" teaches us how to climb the tower to get the power of losing brain cells. My grade is lucky enough to my provided with Desmos as the main math provider. We are only required to use this brain pollution as "advanced math", while the rest of the school has to use it for all of the math classes. I'm disappointed by the fact that they ask you to donate to this $#*!. Whatever nimrod made this can go $#*! themselves.
