GURPS has more math in character gen than about 90% of the hundreds of systems I own. But it's simple math for the most part. The more math games include CORPS, Rolemaster and Champions, Web of Stars, Space Opera... But GURPS itself wasnt the cause for the comment...GURPS isn't math heavy at all despite people saying it all the time. Especially since you don't have to build the airship (like with HERO), your character buys it with points or money. Very simple actually.
GURPS Vehicles is much math, a number of important iterations involving exponents. Best done in a spreadsheet.
