      Multiplication of negative and positive numbers.


      positive x positive = positive


      negative x negative = positive


      positive x negative or negative x positive = negative


      (-3x) (-5x) (2y)


      -3x * -5x = 15x^2 ( 15x squared)


      15x^2 * 2y = 30x^2y


      Answer: 30x^2y
