4×4=12 is the fifth studio album by Canadian electronic music producer Deadmau5, released on December 7, 2010, by Virgin Records, Ultra Records and Mau5trap. The album's title refers to a miscalculation made by Deadmau5 on his Ustream channel, where he mistakenly said that his live setup of four banks of four "equals 12" instead of 16. The album received a nomination at the 54th Grammy Awards for Best Dance/Electronica Album.
