[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
[ Lyrics from: link ]
[All]
Now take off one hundred and add on 24,
Then divide by two and add on seven more

[All]
And if you're struggling now it's not hard to tell
You don't know, your maths skills 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, your maths skills are terrible

[Harry]
It's really kinda pitiful
