mathematical intelligence & aging
My alma mater's mailing list sometimes includes a mathematical brain teaser in their emails. Often, when I first look at the brain teaser, it seems like it should be easy to solve. Sometimes, it is. Other times, it takes me a long time to figure out (or I may even give up, deciding I have other pressing things to do with my time).
I wonder if I could have solved these problems quicker/easier, when I was younger. Or if they would have been the same difficult for me, back then.
Latest brain teaser:
There is a number less than 3,000 that when divided by 2 leaves a remainder of 1, when divided by 3 leaves a remainder of 2, when divided by 4 leaves a remainder of 3, when divided by 5 leaves a remainder of 4, when divided by 6 leaves a remainder of 5, and so on up to nine.
What is that number?
( How I finally solved it )
