    Re: Creating equations

    Hello, Tattilus1!

    I haven't found an equation for 9.

    . . \begin{array}{ccc} 0 &=& \dfrac{5+5-5-5}{5} \\ \\[-3mm]1 &=& \dfrac{5}{5} +\dfrac{5-5}{5} \\ \\[-3mm] 2 &=& \dfrac{5+5}{5} \times \dfrac{5}{5} \\ \\[-3mm] 3 &=& \dfrac{5+5}{5} + \dfrac{5}{5} \\ \\[-3mm] 4 &=& \dfrac{5+5+5+5}{5} \\ \\[-3mm] 5 &=& 5 \times \dfrac{5+5}{5+5} \\ \\[-3mm] 6 &=& 5 + \dfrac{5+5}{5+5} \\ \\[-3mm] 7 &=& 5 + \dfrac{5}{5} + \dfrac{5}{5} \\ \\[-3mm] 8 &=& 5 + \dfrac{5+5+5}{5} \\ \\[-3mm] 9 &=& \\ \\[-3mm] 10 &=& 5+5+\dfrac{5-5}{5} \end{array}


    If we can use "55", then:- 9 \;=\;\dfrac{55-5-5}{5}
