For all m,n,p which are elements of the Integers: (i) If p > 0 and mp < np then m < n (ii) If p < 0 and mp < np then n < m (iii) If m <= n and 0 <= p then mp <= np Any help with the above proofs would be appreciated!

i divide both sides of mp < np by p, and we get m<n. ii divide both sides of mp<np by p. Don't forget to switch the sign, since p is negative. iii multiply both sides of m <= n by p.
