(Duet with Cliff Richards)

Janet: I know we just met, but I feel like I've known
you before

Cliff: But something about you my heart has been
searching

Janet: I don't understand it, it's over my head

Cliff: So don't try to solve it, just feel it instead.
Ooh

Chorus:

It isn't really such a mystery

Anyway you add it up it turns out to be

Attraction automatic, a simple mathematics

Two to the power of love

Janet: I look in your eyes and everything falls into
place

Cliff: You don't have to say it, it's written all over
your face

Janet: By my calculation, I'm falling for you

Cliff: It's a perfect equation

Janet and Cliff: And I know that it's true

Repeat Chorus

Janet and Cliff:

It's complicated, but it's easy to see
A combination that was meant to be
It's something you can count on

Repeat Chorus

It isn't really just a shot in the dark
Somebody must've worked it out on the chart
Attraction automatic, a simple mathematics
