Mathimoto's Real Complaint

My real complaint is I haven't been able to post more.

Alack, alack, alack. And the real victims are you good folk. But even Mathimoto needs a job, and rest assured once the job situation is stabilized, posts will come once more!!!

But in lack of that, let me give you a little play with number, related by the way, to some secret math speculation I'm doing.

If you want to find if a number is divisible by:

2, check if it's even. (Simple enough)

3, add all the digits and see if the sum is divisible by 3, if it is then the actual number is divisible by 3. (That's one of the cooler tricks)

4, if the last two digits are divisible by 4, then the whole thing is divisible by 4.

9, add the digits, and if the sum is divisible by 9, then the actual number is divisible by 9.

Do you see the suggestion here? Maybe there's a relation between numbers and their base 10-representation. Maybe... and maybe I'm getting close to it... maybe...

But what we do know for sure (to quote my good friend Kendrick), is that numbers are awesome.
