I think you should be able to use limits as long as you use lim(x -> infinity), so for like asymptotes. That still leaves room for creativity but it doesn't make place for cheasy tactics like that one . 88 = 44 * 4 / sqrt(4)
4! * 4 - sqrt (4) * sqrt (4) = 92 (gamma (4))! / (4 * sqrt (4)) + sqrt (4) = 92 (as well...) (4! - sqrt (4)) * 4 + 4 = 92 (another one...) (4! - 4 / 4) * 4 = 92 (there seems to be a lot of ways) 44 * sqrt (4) +4 = 92
