Re: maths product
Hi fatty;
It is not wise to just go handing your email address out like that. The asker here might be legitimate but anyone on the internet can see it also. You are leaving yourself open to spammers and hackers as well as numerous bots.
You might have been unaware of that. If you put it back I will assume you are willing to chance it and I will not interfere further.

Re: maths product
Hi maria tan;
The two numbers are 16 and 2.
There are only 3 products that equal 32. 8 x 4 = 32, 2 x16 = 32 and 1 x 32 = 32. Only one of them has a quotient of 8. Welcome to the forum.

Presumably it wants you to find 1x2x3x4x5x6x7x8x9x10x11x12x13x14x15, also known as "15!".
it actually doesn't equall fifteen it equals 3026144400. becuase you have to find out what 1*2 is and the product of that *3 and the product of that #4 and the product of that *5 and keep going until you get to the product of 15.
15! means 15 facturo or something like that which is basically the product of 15

Re: maths product
15! is not the product of 15, it is the product of all natural numbers less than 15. Maybe that is what you meant?

Re: maths product
Hi Umar;
Welcome to the forum. You are correct in drawing attention to the miscalculation.
15! = 1307674368000 not 3026144400

Re: maths product
Hi rstakits!
Using N for "a number" that would be 800 times N, or 800N or 800xN where x means times.
If you have a collection of numbers like {3,10,5} then X{3,10,5}=1x3x10x5=150 would be the
product of the numbers in the collection. We in essence "scale up" the 1 by the numbers in the
set. If there are no numbers in the set like the set { } then we don't have anything to scale the
1 up by so we just get the 1. X{ }=1.
So this gives us a short notation for multiplying any collection of numbers we want. If all the
numbers in the set are the SAME then we have exponentiation. X{2,2,2}=1x2x2x2=2^3, which
is called "two cubed."
That may be more than you wanted, but maybe it will help somewhere along the line.
Have a stupendous day!

Re: maths product
Hi bobbym!
Finally! Patience works. I now have a signature. I'll probably change it to something else before
long since I just put something in the "slot" to see when it would finally appear.
Have a lovely day!
