Simple math our love divided by the square root of pride

Multiply your lies, this time I'm going out of my mind

It was heavy when I finally figured it out alone

And I know I'm wrong sometimes, oh

But it ain't rocket science, no

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 nerve to flirt with her in front of my face

Here's your keys, your bags, your clothes

So now get out of my place

You say I'm crazy and that we're happy

Is that supposed to comfort me?

And I know I'm wrong sometimes, oh

But it ain't rocket science, no

Yeah, 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 the promises flushed

A thousand apologies just

Take out the pain and then 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

Dumb plus dumb equals you

Dumb plus dumb equals you

And I know I'm wrong sometimes

But it ain't rocket science, yeah

I may not be einstein

But I know dumb plus dumb equals you

Simple math our love divided by the square root of pride

Multiply your lies, this time I'm going out of my mind

And I may not be einstein

But I know dumb plus dumb equals you
