construct proofs (in the same fashion that was demonstrated in the video lectures)
to show that the following sequents are valid.
1. (–q --> –p), p ⊢ q
2. (p --> (m --> r), m ⊢ p--> r
3. w--> (s--> (b--> r)) ⊢b--> (w--> (s--> r))
4. –t--> –r ⊢ r--> t

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

faster, im not sure why but i know it is faster

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
