a%28b%2Bc%29=ab+%2Bac is true for each of the
following values of a, b, and c:
a) a=-5, b+=2, c=-6
a%28b%2Bc%29=ab+%2Bac
-5%282%2B%28-6%29%29=-5%2A2+%2B%28-5%29%28-6%29
-5%282-6%29=-10+%2B30
-5%28-4%29=-10+%2B30
20=20...... true
B) a=-2, b=-3, c=4
a%28b%2Bc%29=ab+%2Bac
-2%28-3%2B4%29=-2%28-3%29+%2B%28-2%294
-2%281%29=6+-8
-2+=-2+....... true
