Lyrics of 'Einstein' by Kelly Clarkson

Simple math
Our love divided by the square root of pride
Multiply your lies, plus time
I'm goin' out of my mind
It was heavy when I finally figured it out, alone

I didn't get it the first time (ooh)
But don't think I've been so blind (ooh)
And I may not be Einstein, but I know
Dumb plus dumb equals you
Dumb plus dumb equals you (yeah, yeah, yeah)
Dumb plus dumb equals you (you)

Even had the nerve 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? (Oh, yeah)

I didn't get it the first time (ooh)
Don't think I've been so blind (ooh)
Yeah, I may not be Einstein, but I know
Dumb plus dumb equals you
Dumb plus dumb equals you (yeah, yeah, yeah)
Dumb plus dumb equals you (you)

All of your promises plus
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 (ooh)
Without you, I'm just fine (ooh)
Why did it take me so long to figure out
Dumb plus dumb equals you? (Ooh)
Equals you, yeah

I didn't get it the first time (ooh)
Don't think I've been so blind (ooh)
Yeah, I may not be Einstein, but I know
Dumb plus dumb equals you
Dumb plus dumb equals you

Simple math
Our love divided by the square root of pride
Multiply your lies, plus time
I'm going out of my mind
And I may not be Einstein, but I know
Dumb plus dumb equals you
Equals you
