        The goal of this game is to create the required equation solution by writing the left side of the equation.
        Your equations do not follow the order of operations, but rather follow the order you entered the numbers.
        If you did 3*4+2*5 that would be like 12 + 2 = 14 * 5 = 70 rather than 12 + 10 = 22.
        Entering numbers
        Each number you enter must be a single digit.
        The calculator has numbers 1 through 9 but does not have zero since it would generally be of little value in entering single digit numbers.
        You can repeatedly enter the same number. If you had to solve =8 you could do 4+4, 2*2*2, or any other variation to solve it like 5+3.
        Strategy
        Each time after you enter a number the calculator automatically updates the result to less you know what number you are at so far.
        Early in the game you can use addition for the early numbers, but as you progress it makes sense to use multiplication to get close to the final number & then use addition to add a bit more to reach the desired quantity.
        When numbers are below 90 you can multiply 9 by the nearest multiple & then add or subtract the difference.
        When numbers get over 100 you can multiply 3 numbers together (e.g 3*4*9 or similar) and then add or subtract once or twice to reach the final quantity.
        Scoring
        Near the top of the calculator there is a green bar which is a time meter.
        You must solve the equation before the timer reaches zero or it is game over.
        Each time you solve an equation you get another solution you must solve and the timer is reset to full.
        If you finish with a lot of time left on the meter you can score as many as 3 coins & if you barely finish in time you earn a coin.
        Target Audience
        The game is suited for players who like fun mathematics games.
        The game has no adult themed content.
