One Direction - Math Song lyrics

[Liam] You're insecure, so half of four, Your old brains are not what they were before, [Zayn] Add two threes, it's fine for us, 'Cause we're young and we can still remember stuff [Harry] Everyone else can multiply by 60, Everyone else can add two [All] And Now take off one hundred and add on 24, Then divide by two and add on seven more And if you're struggling now it's not hard to tell You don't know, (o oh) your maths sk**s are terrible [All] If only you had a mind like me You'd understand how to divide the sum by three, And then just add on the age of this OAP You don't know, (o oh) your maths sk**s are terrible (o oh)
