歌词：
Let's play with numbers
Tell me the answers now!
It's time to play with numbers!
I know you know how!
Five times six?
Thirty!
Thirty divided by three?
Ten!
Ten plus ten?
Twenty!
Thirty minus ten?
Twenty...again!
Let's play with numbers!
Tell me the answers now!
It's time to play with numbers!
I know you know how!
Five times four?
Twenty!
Twenty divided by two?
Ten!
Ten plus five?
Fifteen!
Twenty minus five?
Fifteen...again!
Let's play with numbers!
Tell me the answers now!
It's time to play with numbers!
I know you know how!
