    A negative number(-6) * a negative number(-4) will always equal a positive number(+24). Same with division. A negative number(-24) / a negative number(-6) will always equal a positive number(+4).


    Negative Rules:


    Multiplication and Division


    -5 * -7 = 35


    -5 * 7 = -35


    -35/-7 = 5


    -35/7 or 35/-7 = -5


    Addition and Subtraction


    -9 + -5 = -14


    -9 + 5 or 5 + -9 = -4


    -7 - (-5) = -2  >  you cannot minus a negative, the number will become positive.


    -7 + 5


    6 - (-5) = 11


    6 + 5


    All positive numbers the answer will be positive.


    8 + 9 = 17


    17 - 8 = 9


    6 * 7 = 42


    42/7 = 6
