Given:

u>v and t>0

This means that 't' is definitely a positive integer.

**For**

**ut>vt**Divide both side of equation by t, we get

u>v (already given)

Hence, this is true.

**For u+t>v+t**Subtract t from both sides of the equation, we get

u>v (already given)

Hence, this is true.

**For**

**u-t>v-t**Add t to both sides of the equation, we get

u>v (already given)

Hence, this is true.

u>v (already given)

Hence, this is true.
