      Inequality

Properties of inequality

•If 4 < 6 then 4 + 2 < 6 + 2 (6 < 8).

•If 10 < 15, then 10 - 3 < 15 - 3 (7 < 12).

•If 2 < 4 and c = 3, then 2×3 < 4×3           (6 < 12).

•If 2 < 4 and c = -1, then 2×(-1) > 4× (-1) (-2 > -4).

•If 8 < 12 and c = 4, then   ??      <  ????  (2 < 3).
                             ??         ??

•If 8 < 12 and c = -2, then   ??     >  ????  (-4 > -6).
                             -??        -??
