A method of playing a mathematical game to calculate a target value includes generating the target value randomly, generating a plurality of calculating numbers to be used to calculate the target value, and calculating, by a first player, an initial solution that is equal to the target value, by combining the calculating numbers with any combination of a plurality of mathematical operations in any order. The calculating numbers can also be generated randomly and the plurality of mathematical operations includes addition, subtraction, multiplication, division, powers and roots. If the first player fails to attain the initial solution equal to the target value, then an alternate solution is attained by the first player that approximates the target value. The second player then uses the same previously generated calculating numbers, with a second different combination of the plurality of mathematical operations in any order, to calculate a second solution that is equal to the target value, or more closely approximates the target value than the first player. The game continues until the target value is attained, or a final value is attained that most closely approximates the target value.
