I found this number in my dads jewelry box after he passed away. Multply this number by 2, 3, 4, 5, 6 and examine your answers. I think you will find them interesting. And then multiply by 7. Once you get past 7 (8, 9, ..37, 38 .. etc.) If remove the first digit in the result and add it to the last digit, you end up with the same effect. What in the world is going on here? Any UHH math majors that can explain? Show this one to your youngsters.

These types of puzzles always intrigue me. This one, however, is beyond my expertise. I tried to play with it and find some kind of repeatable pattern, but came up empty. Great stuff.

How about this--- Hey Algebra, quit telling us to find your X. She is gone and we don't know Y. Silly - Yes I know.

Here's my take on the beauty of mathematics. I'm a senior in mechanical engineering, so I've seen quite a bit of math in the recent past. We find patterns in math because it is a reflection of its Creator. Math always yields the correct answer out of an infinite set of possible answers, because that is what its Creator is like. It's like reaching into a vault full of an infinite number of keys and pulling the right one out for the door at hand, every single time. Math has an element called infinity that the most brilliant mathematicians do not understand, just like God Himself. Patterns? We find them throughout Creation, including math, because our God is creative and not chaotic. If we could somehow get a grasp on all the aspects of puzzles like these patterns or infinity itself, I think math would lose some of its wonder and beauty. By the same token, if we could somehow grasp the love and character of God, we would lose the wonder that always goes hand in hand with things we do not understand.
