This is probably, really simple, but I can't wrap my head around it.
#83, page 72: on the OG math workbook
If u > t, r > q, s > t, and t > r, which of the following must be true?
I u > s
II. s > q
III u > r.
case II and III, are straight forward and easy.
I drew the number line it looks like this:
Q------------r-----------t-------------u----------
The question is: where is 's' placed? between 't' and 'u,' or just in front of 'u'?
case I explanation tells me to draw the line, and plug in some arbitrary numbers. they pick, t = 2, u = 3, and s = 4, therefore it's obvious that u is not greater than s.
How did they come up with these numbers? what if I pick t = 2 u = 5, and s = 4? then U > S, and still follows all the premises...right?
What am I missing here?
