OE


Point (a, b) is in the second quadrant where points have signs of (–, +); thus, a is negative and b is positive. Point (c, d) is in the third quadrant where points have signs of (–, –); thus, c is negative and d is negative. So, Quantity A is a positive times a negative, which is negative. Quantity B is a negative times a negative, which is positive. Quantity B must be greater.
