1 = -10080
2= -1
3= 1848
4= 131
5= 0
6= (12/5)(6/3)=72/15 (4/9)(8/11)=32/99 72/15+32/99=7128+408 / 1485=7536/1485
7=14/3+15/2=73/6 - 6/4=266/24=133/12
8= (((12/5)(15/4)=180/20 / (13/7)(16/9)=208/63 180/20 / 208/63=11340/4160 (-5)= -2835/208 + 1/2=2731/208
9=(13/22) / (43/15)=195/946 - 16/7= -13771/6622
10=(9/8)(8/6)=72/48 / 25/4)=288/1200 + (13/45)(45/2)=585/90 + 288/1200=727920/108000=337/100
11=(33/17)(45/12)=1485/204 + 3/5=2679/340 - 18/7=12633/2380 + 16/9=151777/21420 - 25/5=223385/107100
