Math Is Fun Forum

Well, we had fun trying. But this one is headed for the circular file.

I hope random_blonde can tell us what her teacher reckons the answer is.

Probably involves standing a 6 on its head

Exactly ... we are happy to make it better, but you gotta tell us HOW.

Inifinity. A number SO BIG that you can't ever reach it. 

Some people say it is the number that is equal to the largest number you can think of plus one.

So, we know what 1/10 is, we know what 1/100 is, we know what 1/1,000,000,000 is (one billionth), but what is 1/Infinity?

Hi, mathsyperson. Good to have you on board.

Doesn't matter. A puzzle is a puzzle.

And this one is tough.

I have tried fibonacci, primes (only 487 is prime), powers, multiplication, and they all have random results.

I am thinking either
a) you can never guess the two numbers but you can guess their product, or
b) it needs to be decoded somehow (words, letters or something)

I tried dozens of combinations and none of them work ... it may be impossible to do following those instructions!

That's good, cool_me ... I never knew that education so neatly included the vowels.

I will have to remember that!

Noone likes "Cafe Infinity"?

"what is the number of prime numbers between one and a million that become a perfect square if you add 1 to them?"

Surely the number 3 qualifies ... add 1 you get 4 which is 2*2

So the answer is 1, isn't it?

I think he got confooseded and started a new topic when he should have continued a previous one.

Indeed!
