Near a small farm, a portal opened from which mutants from a parallel universe appeared. They move in a large crowd towards the farm in order to level it to the ground and destroy all its inhabitants. In the game Math Farm you will help the animals living here to keep the defenses. In front of you on the screen you will see your character, who will stand on the road with weapons in his hands. Monsters will move in his direction. When they reach a certain point, a certain mathematical equation will appear. You will have to solve it in your mind. The numbers will be visible below the equation. These are answer options. You will have to select a number with a mouse click. If your answer is correct, then your character will shoot from his weapon and destroy the enemy.
