RevEarth

Each level has different number of equations to be answered depending on the difficulty. The user is given one (1) minute to answer the set of questions per level. On the last level of each scene, there is a bonus three (3) seconds on each correct answer that will be added to the time as a reward for the user. But for every wrong answer the user will lose five (5) seconds of his/her time. Each scene uses one of the basic mathematical equations: for the ocean scene, addition is applied; for the mountain range scene, uses subtraction; the river scene, multiplication; lastly the forest scene is for division. The user will be able to see his/her progress on each scene using the “scenes cleared” button that the user will see on top of the four (4) scenes.
