Honestly, I'm very happy. However, I'm not sure how this should affect my view of myself as a writer. Is it simply topical, or do I really have an eye-catching, thought-provoking fist? I think that I need to try something other than math or the gospel. I'm not sure what, though...
If we assume that kids in Utah lose teeth at the same rate as all other children in the world and that each day in the year is just as likely as the rest to lose a tooth, then we have that of the alleged …
I read an article by Brad Rock this morning where he quoted heavily from Dr. Thomas Forsthoefel who was giving his opinion on religious institutions being involved in sports. BYU, of course, came up. I think Forsthoefel came off sounding a bit misinformed about the culture, drive, mission, etc. of BYU. Below is the email that I sent to Brad Rock this morning after finishing the article: Brad - That was an interesting article. I tend to disagree with Forsthoefel, though, or at least disagree with what I may have read into his comments. A quote in your article says: "There may be a kind of growing pain. BYU is in the real world and the real world works on Sunday. Can we (BYU) live with the adjustment? I'm empathetic with that, whatever decision is made, people are going to be unhappy.… Some will say get with the program, we'll be OK at the next level, others will say we've sold out and we've made a deal with the world."

So, here are strategies for discovering divisibility from 2 to 10, and then we'll talk about some rarer, more surprising divisibility tricks:
Divisible by two:If the number ends in 0, 2, 4, 6, or 8, it is divisible by 2.
Divisible by five:If the number ends in 0 or 5, it is divisible by 5.
Divisible by ten:If the number ends in 0, it is divisible by 10.
Divisible by nine: If you add all the digits in a number together and that new number is divisible by 9, then it is also divisible by 9.
Example #1: 189 -> 1 + 8 + 9 = 18, 18 is divisible by 9, so 189 is also divisible by 9 Example #2: 137781 -> 1 + 3 + 7 + 7 + 8 + 1 = 27, 27 is divisible by 9, so 137781 is also divisible by 9 (Note: If adding six numbers together in your head seems difficult, look for my next post on number-grouping tricks. Soon, adding six numbe…
