If x < y < 0, which of the following must be true?
Choose one:	A) 2x+y is a negative integer	B) 2xy is a negative integer	C) x-y is a positive integer	D) (-x)+ (-y) is positive integer	E) x/y is a negative integer
Given x, y are less than 0. So both will be negative integers   negative + negative = negative   negative * negative = positive   negative / negative = positive   x-y is false since xSo, option (-x)+ (-y) is positive integer is true , because if we multiple negative number with negative it becomes positive(x, y are negative numbers)   Answer : (-x)+ (-y) is positive integer
