When the Product is One
Harry Guffee

This song is available on Harry Guffee's Doggone Math. 

Two numbers are reciprocals
If their product is one
Multiplicative inverse
The product is one

Four times one over four
Three times one over three
Two times one over two
The product is one


Three over four times four over three
Two over one times one over two
Y over X time X over Y
The product is one
