Lol i forgot about 0
hands up all those who opened up teh calculator!
hahaha--I didnt have a clue what "find the product of" meant until I looked at the answer. And THEN I open the calculator and figure it out.
It should've been put in two categories this teaser! (math and trick) (And confusing)

Nice.... but a little confusing.... I thought the teasermeant two numbers on a phone multiplied together... not all the numbers on a phone..... but still good one!
urgh... i forgot 0 nice trick
This belongs in the "trick" section
i got it right, but it should be in the trick catogory
Trick...
thats a good one!
if it was in the trick section, it would have been too easy
I thought you deserved a calculator, it's not in trick section.
Reminds you about zeros.
Reminds you about zeros.
I believe zero, technically speaking, is not a number.
It means, "What is the answer when you multiply all the numbers on the telephone?"
Now do you understand?
Oh, and I'm not too technical
Now do you understand?
Oh, and I'm not too technical
that was actually really easy!
Technically you are wrong!!!!
You said NUMBERS, you did not say numeric characters.
The zero is NOT a number, it is the lack of a number. If you want to argue this point, first ask yourself how many people begin counting starting with zero.
If you still want to argue the point, go to the following link and argue with them:

I know we see zero as a number on a calculator, but it is a NUMERIC CHARACTER that is provided in order to type 10, 20, 30,...which are numbers.
But 0 by itself is not a number.
So the real answer to the question that you asked is:
362880
I hope im not the only one here that knows this, or i'll feel like a total brainiac nerd.

That was very easy.
And yes, zero is a number. There are several types or sets of numbers. Zero is an Integer, a Real Number, and a Rational Number. About the only set it doesn't belong to is Natural Numbers.

I also agree that this belongs in the Trick Category as some would include the 0 as a number and some would not. Tricky one!
i agree with fsullivan.
it has to do with math.
it has to do with math.
easy if you know what product is, and what a number is, and which numbers count as numbers!!
but it was a great teaser, stumped many...but not me!!

i got it but good teaser!
How can you say zero is not a number.It is.If you say that 0 is just a numeric character for 10, 20 etc. then even 1,2,3 are numeric characters only.
Those who say zero is not a number belong to primitive ages.

everyone knows zero is a number. duh!!!!!!!!!

I GOT IT!!!!!!! I LIKED THIS ONE!!! haha
Zero is a number. It's even included in the set of numbers named "whole numbers", which ought to silence any attempt at symantec nonesense to argue otherwise.
This one is way too easy even with the "trick" aspect. (Shame on you if you opened the calculator.)

omg, people, open a 5th grade grade textbook and turn to the chapter "Number Theory". It clearly states that zero IS a whole number (as stated above) though it is not a natural number. sheesh!
I thought I was supposed to add them together.
Well I went and got 362880 and I felt all proud of myself and then I opened up the hint and I was like "oh... no... it...is...not. ARRGGHHH". So I got it right but I went through all that trouble for nothing and I am MAD. Ooops I forgot I should be grammatically correct. For all you British people or people that are from a country where people use there brains for grammar and other good thingys like that I meant that I am angry, not insane. I have got to stop saying mad. Language Arts may soon stop being my favorite subject.
I know I may act like I belong in a mental institution but trust me , I don't.
dude will prolly never see this but. to timalee. zero may not be counted in a simple 1-10 count. but zero is THE WHOLE NUMBER between -1 and 1. so if I began my count with -2 and worked my way up. 0 would absolutely be in my count. zero is NOT the same thing as white being all colors and black being the absence of color. zero is measurable. -1938373 is measurable. until you start getting into irrational numbers, any combination of the digits 1234567890, whether it be only one or an infinite number of them together, every single possibility is a measurable number including zero. so while that was an interesting yet, completely fabricated argument, it is also 100% wrong.
