Hmm... first time I saw this, I thought. pffttt, easy. Then I actually read the question.

Anywho, the numbers in the triangles are all primes I think... its a start?

[.:Requiem:.]

No, they aren't all primes...

I'm gonna have to work on that when I get a chance

Hmm. Took me a few minutes pursuing false leads. It isn't *entirely* mathematical.

At least, I don't consider digit-swapping to be math.

At one point in the process, you have (as a result of basic math) a two-digit number -- for example (not used in any of these triangles), 78. You would then change that to 87 before going on to the next (basic math) step.

Is that enough of a hint?

Edit: Actually, that would have been a pretty good LC (although easier than recent ones).

Psh. It would be too easy.

The answer is my age doubled minus my sister's age plus my cousin Douglas's age.

Hmm..... Since you are 55.... I'm guessing the answer would be 175?
(Haha! I was joking!)

This is the answer

HAH!Did you think you'd get it that easily?

Kidding. Its 30.Multiply the bottom two, reverse digits, then add the top.

[CWisgood]

The real answer is

First, multiply the two numbers below. Then, reverse the ten digit and the single digit. After that, add the top number. simple enough?

thank-you CW!!!
