Number Nine will put you on the spot
Number Nine will tie you up, oh, in a knot
When you're tryin'
Multipyin' by nine,
You might give it everything you've got
And still be stopped
If you don't know some secret way you can check on,
You'll break your neck on
Naughty Number Nine

Now the first thing to keep in mind
When you're multiplyin' by nine
Is that it's one less than ten
You see nine is the same as ten minus one
So you could multiply your number by ten,
And then subtract the number from the result,
And you'd get the same product
As if you'd multiplied by nine
And you knew it

I mean 8 x 9 is 80 minus 8,
And 7 X 9 is 70 minus 7, and 6 x 9 is 60 minus 6
You could use those tricks
'Cause you must have some secret way you can beat it,
or else you'll meet it
with Naughty Number Nine

Of course it doesn't hurt
to know the table of nines by memory
It goes like this:
1 x 9 is 9, and 2 x 9 is 18
(Mean old Number Nine)
3 x 9 is 27, and 4 x 9 is 36,
5 x 9 is 45, and 6 x 9 is 54, and 7 x 9 is 63,
8 x 9 is 72, and 9 x 9 is 81,
and 10 x 9 is 90

Now the digit sum is always equal to nine
I mean, if you add 2 and 7, the digits,
You get 9, the digit sum
That's true of any product of 9
If they don't add up, you've made a mistake

'Cause you must have some secret way you can check it,
Or else you'll wreck it
With naughty, nasty, mean old Number Nine
