Me and Kaleigh worked this out in S.E and the answer is “10″
It was pretty easy on the Lockers website but when we tried it on paper it was Very Hard. =)
We are still working on “Is the number 1 a prime number ?”

Well done to those of you who tried this, either manually or using technology!
Ashton thinks that is “easy on the website but hard on paper”.
In class we will try it using only the power of our brains - to think the problem through and arrive at an elegant mathematical solution that requires neither technology nor reams of paper!!!

I did it on the link that you put on the website, and the answer was 10. It was easy to do on the website, it would be really hard to do it on paper!
