Don't make me laugh, ofcourse I can, using logical ways of calculating such trivial amounts are easy to calculate. By the way, I worked with a guy from India, would could add millions in his head, and his IQ was onlt 128. When I go shopping for groceries with my wife, I always tell her exactly what the total of her groceries is, ofcourse because I am not under obligation sometimes I am a couple of pence out. Tee hee!
