A method for providing a number game using four arithmetical rules is provided to make a user hit a number corresponding to a problem by irregularly displaying a plurality of number boxes and arithmetical symbols in a screen, and designing a formula with arrangement of the number boxes and the arithmetical symbols by direction keys. The number boxes and the arithmetical symbols are displayed in the screen of an electronic device. The user designs the formula for calculating the number corresponding to the problem by vertically/horizontally arranging the number boxes and the arithmetical symbols with the direction keys. The arranged formula is calculated. It is judged whether a calculated result is matched with the number corresponding to the problem. |
