Seesaw ratio of mathematical inequality application problems
Now we know S>p and R>, so the next step is to know the relationship between P and Q,

If p; R can be equal.

But if Q>p and S> hold together, the result of the second seesaw is: P+R > Q+S will not be realized. There are contradictions.

So p must not be greater than q, and it will not be equal to it in the same way.

So P>Q, then from Q+R=P+S, s

Therefore, the order is R>S>P>Q.
