Which of the following is **not** true if *h*, *m*, and *k* are integers and

*h*<

*m*<

*k*< 0?

*m**k*<*h**k**m**h*<*k**m**h*+*k*<*m*+*k*- 0 <
*k*–*h*

Multiplying both sides of an inequality by a negative integer reverses the sense of the inequality, so (b) is false. The other statements are true.
