## Solve this if you are a genius

This “solve this” quiz showed up on my Facebook news feed.

8 = 56

7 = 42

6 = 30

5 = 20

3 = ?

The pattern looks pretty easy, right?

8 × 7 = 56

7 × 6 = 42

6 × 5 = 30

5 × 4 = 20

So what is the correct answer?

Here’s mine:

3 = 3 — even if it’s preceded by a bunch of false statements.

Do you agree?

**Update**. This is an *old* post and I thought it had seen all the life it was going to see. Then Angel comes and leaves a comment:

It turns out that the ‘?’ can be whatever we want it to be!

Angel backs up his claim with math. I think we have the definitive answer.

## XKCD: All the Fun Parts of Life are Optional

I *love* the mouseover text:

“The only things you HAVE to know are how to make enough of a living to stay alive and how to get your taxes done. All the fun parts of life are optional.”

Keep learning. :-)

## Happy Pi Day

Happy Pi Day!

I found Dinosaur Comics’ Pi Day comic to be less violent than the Abstruse Goose Pi Day comic I posted a couple of years ago.

I’m looking forward to July 22 (and sorry I “missed” February 71).

How many digits of pi do *you* know?

I still don’t know pi beyond 3.1415926, but thanks to Randy Yaw, Mr. Pi Day himself, I know that I can enter the pi character on my computer using ATL-227 (notice the numbers are the same as 22/7, the approximation for pi).

## Happy Pi Day

Have a slice of pi!

*way too many*digits of pi. It is just the failed humor (okay, the reposting of failed humor) by one who can’t remember more digits of pi than 3.1415926.

Sorry, Randy…
