Hey Dog, is that a firm maybe?

That is a firm "I don't know, and I refuse to cheat by using a calculator."

Test your primitive non-calculator skills. Can you determine in thirty seconds if the number

4890767566789657453424859065646348799

is divisible by 3? Is it?

No

I use the same method for figuring oil changes on my car(s). :p

Okay, class over.

The simple, primitive and easy way is.......

1. Strike through all zeros.

2. Strike through all threes, sixes and nines.

3. Strike through all remaining sets of digits that add up to numbers that are divisible by three; e.g. 8+4, 5+5+5, 7+7+1, 2+1, etc.

If whatever remains is not zero, the answer to whether the number is divisible by three is NO. If no digits remain, the answer is YES.

Try it.........

Regardless of what's in front of it, if the last digit (or pair of digits) is a factor of 3, it's generally divisible by 3.

Easy peasy.

I can't believe I read that whole thing.  I'm going to make my husband read it so he can have a headache, too.

Payments to foreign governments must be reduced, if the nation doesn't want to go bankrupt. People must again learn to work, instead of living on public assistance.”

Easy Mr. DumbAss, when I begin to speak of Obama  in a kindly view point, then I have had a Minnie stroke. A minor stroke is when I begin to speak of old Joe Biden as a statesman.  A middling stroke I will begin to extold all Barney Frank has done for us.

A major stroke is when I am carted off muttering about some Nebraska Coach that sleeps naked, and owns cats.

Whoa.

I just got around to reading this thread.

It's, uh, not quite what I'd expected; I hadn't checked to see who the original poster was.

Well now, I thought a Minnie stroke would be when you started wearing a bow on top of your head and your ears got really, really big...
