Frank Ocean "Math"

Frank Ocean 'Math'
Following the circulation of previously unreleased track "PDA" yesterday (April 9), Odd Future's Frank Ocean has let loose another oldie from the vault, this time in the form of R&B jam "Math."

A snippet of the song surfaced on Fashionably Early's Tumblr late Friday night (April 6), but today, the hip-hop blog has finally unveiled the track in full.

While "PDA" -- recorded under Ocean's early moniker of Lonny Breaux -- was used as a demo for the Backstreet Boys, it's unclear as to whether "Math" was referenced by another artist. But what is clear is that the crooner's smoothness knows no bounds, even when referencing calculus. Take a listen below.
