7 ---- \ / 1 <- *note: the 1 should be more to the right. ---- N=3 Ok, this might be dumb , but it think the answer for this is 1 but i'm just making sure. cuz i know that for example if it is 7 ---- \ / N <- *note: the N should be more to the right. ---- N=3 the answer would be 3+4+5+6+7 but if it is just a 1 there, then is it just 1? i mean the N doesn't really matter because N isn't present as a variable on the right side. Thx guy, Mike.
