You ask me how I can be so sure My love for you will endure Right here and now I'll show you how I know I just take this pen here in my hand Set down and equation, understand By the time we find the bottom line, you'll see How much you mean to me One plus one is two (it's mathematics) No dividing me and you (the numbers don't add up) When I'm minus you There's no solution It's as simple as can be (it's mathematics) Like the sum of you and me (two times ecstatic) Just the right amounts And that's what counts Mathematics (mathematics, oh mathematics) Night after night, I'm staying up late Working with my slide rule trying to calculate The good you've done What's to come of us The tears, the talk The fights, the fun They're just parts of a puzzle adding up to one Like a hand or heart You're a part of me Let me show you what I mean One plus one is two (it's mathematics) No dividing me and you (the numbers don't add up) When I'm minus you There's no solution It's as simple as can be (it's mathematics) Like the sum of you and me (two times ecstatic) Just the right amounts And that's what counts Mathematics (mathematics, oh mathematics) Once in your life you happened To Be in the right place at the right time Three little words Can change your mind Four the better (it's mathematics) It's as simple as can be (it's mathematics) Like the sum of you and me (two times ecstatic) Just the right amounts And that's what counts Mathematics (oh mathematics) One plus one is two (it's mathematics) No dividing me and you (the numbers don't add up) When I'm minus you There's no solution It's as simple as can be (it's mathematics) Like the sum of you and me (two times ecstatic) Just the right amounts And that's what counts Mathematics (its mathematics) No dividing me and you (the numbers don't add up) When I'm minus you There's no, no solution It's as simple as can be (it's mathematics) Like the sum of you and me (two times ecstatic) Just the right amounts And that's what counts
