Math Round. As the name suggests this math game simulates a tense math quiz environment. The premise of the game- You are given an arithmetic expression with either the numbers or the signs omitted and the target answer. Your task is to figure out and fill in the missing signs or numbers by dragging them onto their corresponding positions in the expression to make the expression equal to the given target. All this is against the clock.
