18 + (6/15) - (7 + (4/5))
11 + (6/15) - (12/15)
11 - (6/15)
11 - (2/5)
10 + (3/5)
So it's 10 3/5.

hint 4/5 = 12/15 (why) 7 = 7 x 15/15 and 18 = 8 x 15/15 (why) as quickly as you have a large type of "a million/15" s you are able to upload all of them get N/15 divide N via 15 and get M + r/15 get the belief? opps my mistake, subtract rather of upload
