4×4=12 (Four Times Four Equals Twelve) is the fifth album by Canadian electronic artist deadmau5 (his third mainstream album). It was released worldwide (except in the U.S.) on 6 December 2010 through Virgin Records. The album was released in the United States on 7 December 2010 through Ultra Records. The album's name, '4x4=12', was not predetermined but realized after deadmau5 was talking on Ustream explaining his set up for his live shows stating, "Yeah, [the setup] is in four banks of four, and that equals 12," then everyone at Ustream responded to his remark, "Dude, that's 16!".
