Swipe the equation of the current answer. Pretty easy, my grannie got it on her second try. The main reason I made this app is to reduce doom scrolling with something that is more productive but also frustrating enough that after a while you want to go back to focusing the task at hand. Our mission at BlueJai is to come up with creative solution to modern problem and always keeping the users at the forefront. Hope you love the app and it makes you a little sharper at math.
