Whoops - I need to get my eyes checked - you've got -15 there, not 
15 - I had checked my solutions against the wrong problem! :-)

3 * (37/7) + (-34/7) = 11
111/7 - 34/7 = 11
77/7 = 11
11 = 11

and

37/7 - (2 * -34/7) = 15
37/7 - (-68/7) = 15
37/7 + 68/7 = 15
105/7 = 15
15 = 15

Thanks very much for the help, and for the recommendation - I will 
look into Schaum's.
