[Verse 1] Simple math Our love divided by the square root of pride Multiply your lies plus time I'm going out of my mind It was heavy when I finally figured it out alone [Chorus] I didn't get it's the first time But don't think I've been so blind And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you [Verse 2] 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? [Chorus] I didn't get it's the first time But don't think I've been so blind And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you [Bridge] All of your promises plus 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 + dumb = you [Chorus] I didn't get it's the first time But don't think I've been so blind And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you And I may not be Einstein but I know Dumb + dumb = you Dumb + dumb = you
