Simple math
Our love divided by the square root of pride
Multiply your lifeless time
I'm going out of my mind
It was heaven when I finally figured it out alone

Didn't get it the first time
But don't think I've been so blind
And I may not be Einstein
But I know
Dumb plus dumb equals you
Dumb plus dumb equals you
Dumb plus dumb equals you

Even had the nerves to flirt with her in front of my face
Here's your keys, your bags, your clothes and now get out
of my place
You say I'm crazy, and that we're happy
Is that supposed to comfort me?

Didn't get it the first time
But don't think I've been so blind
And I may not be Einstein
But I know
Dumb plus dumb equals you
Dumb plus dumb equals you
Dumb plus dumb equals you

All of your promises, flushed
A thousand apologies, just
Take out the pain and let it leaves us
With nothing at all, no, nothing at all

You can stop wasting my time
Without you I'm just fine
Why did it take me so long to figure out
Dumb plus dumb equals you, equals you

Didn't get it the first time
But don't think I've been so blind
And I may not be Einstein
But I know

Dumb plus dumb equals you, equals you

Simple math
Our love divided by the square root of pride
Multiply your lifeless time
I'm going out of my mind
And I may not be Einstein

But I know Dumb plus dumb equals you, equals you
