This is how I see it, 30 + 21, doesn’t come up that often obviously, but also we don’t have to love every composite number. In fact, we hates most of them. Add 51 to the pile.

Reading the beginning of your comment, I was sure you'd end it with "depends how brave you are".

Dammit, it was right in the post, why did that take me so long?

All the magic goes when you understand it's 30+21

Oh yeah? Then what's 34 divided by 17, smart guy?

Wait until they find out 68 is also divisible by 17.

When I was young I learned that when you add up all the numbers if that number is a multiple of 3 than the original number is also divisible by 3. So 51, 5+1=6 and 6 divisible by 3 and so must 51.

Why? 19 is 15+4 but is still prime?

[verito@lemm.ee]

Because 30 and 21 are both divisible by the same number, 3.

I always thought it's 31+20

Exactly 3(10+7)
