Number nine
will put you on the spot
Number nine
you up
in a knot
When you're trying,
multiplying by nine
You might give it everything you've got
And still be stopped
If you don't know some secret way you can take on
You'll break your neck on Naughty number nine
Now the first thing to keep in mind When you're multiplying 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
Then subtract the number from the result
And get the same product as if you'd multiplied by nine
And you knew it!
I mean!
Eight times nine is eighty minus eight
And seven times nine is seventy minus seven
And six times nine is sixty minus six
You could use those tricks
But 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 times table of nines by memory
It goes like this
So one times nine is nine
Two times nine is eighteen
Mean old number nine
Three times nine is twenty-seven
Four times nine is thirty-six
Five times nine is forty-five And six times nine is fifty-four
And seven times nine is sixty-three Eight times nine is seventy-two
Nine times nine is eighty-one And ten times nine is ninety
Now the digit sum is always equal to
nine I mean if you add two and seven,
the digits,
you get nine,
the digit sum I never dug it,
but the math cats say it's
true Cause you must have some secret way you can
check it Or else you'll wreck it with Naughty
nasty mean old number nine
