The equation formed is: 2y+yz+z -(y+3yz+z) =2y+yz+z-y-3yz-z =-3yz+yz+2y-y+z-z =-2yz+y The rules that we have to use r that: - × - becomes + - × + becomes - + × - becomes - And last but not least + × + becomes + And the second rule we have to follow is also that the number with a variable always comes first. Later all the double and the single variables r placed.
