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 

And I know I'm wrong sometimes 
 But it ain't rocket science 
 And I may not be unstopped 

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 
 Is she a key, ship back your clothes and now get out of my place 
 You said I'm crazy, now we're happy 
 Is that supposed [bad word] me? 

And I know I'm wrong sometimes 
 But it ain't rocket science 

And I may not be unstopped 

Dumb plus dumb equals you 
 Dumb plus dumb equals you 
 Dumb plus dumb equals you 

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

You can stop waisting my time 
 Without you I'm just fine 
 Why did it take me so long to figure it out 

Dumb plus dumb equals you, equals you 

Dumb plus dumb equals you, equals you 

Simple math 
 Our love divided by the square root of pride 
 Multiply your lifeless time...
