Use A and D to go to the right spot on the number line. The number line is split into 10 sections (0%-9%, 10%-19% etc). You have to quickly solve one of the 16 math problems shown on the bubble of the jumping bubble monkey named John, for example, 2/3 would be 67%, and go to the corresponding spot, which, for the example, would be the 60%-69%. You also get 2 tries per number.
