Numbers are random and it's always possible to create at least one equation. Both sides of the equation can have mathematical operations. So, '7+2 = 8+1' or '7+2 = 9' would also be valid. Mathle offers two modes: arcade and survival. ARCADE MODE Equations with more numbers bring more points. Gather as many points as you can before the time runs out. SURVIVAL MODE Invalid equations take a life. Valid equations reset the timer. Gather as many points and survive as long as you can. Good luck, have fun and improve your math skills.
