Be careful! He might want to Rock the New Year, even if Times Square will be covered with paper.

Working in a scissors reference is left as an exercise for the reader.

### Merry Christmas 2015

(Click on the comic if you can't see the full image.)

Merry Christmas! Answers on New Year's!

This was an interesting exercise for me, too. Besides finding good words to use, I originally had eight words, but then realized I only needed seven of them.

After that, I realized that I could have used even fewer if I employed ratios into the mix because the puzzle doesn't actually require you to find all the individual letters.

For example, if you knew the product of CL or CLU without knowing what, say, C was, you would be fine. But I didn't want to use the word CULT in a Christmas puzzle.

If anyone wants to submit a list of fewer than 7 words which can be used to solve this puzzle, I'd like to see it.

Merry Christmas!

### Twelve More Than Two Times X

(Click on the comic if you can't see the full image.)

The song should be longer ... but does anyone really need more of it? The trend is the ''mini lesson'' now, right?

And here are the lyrics, just so they'll be searchable:

Twelve more than two times x gives you eighteen
Doesn't take a lot of work to see
If you use some inverse operations
Then you can solve for x, and it is three.

You subtracted twelve from both sides
And the eighteen became six.
Then don't forget to do division
And you've figured out the work in a few ticks.

(And you know you must do checks!)
You must order operations
After substituting numbers in for x!

Twelve more than two times x gives you eighteen
Doesn't take a lot of work to see
If you use some inverse operations
Then you can solve for x, and it is three.

Merry Christmath!

### Strange Square Roots

(Click on the comic if you can't see the full image.)

Do NOT show my students this! They might think it's a rule and not a curiosity!

In fact, as strange as it looks, it isn't the only mixed number that has this property. And there isn't any reason to drop a jaw to the desk to figure out the pattern.

Let x be the whole number and y be the fraction (between 0 and 1, exclusive).

Then the equation says that (x)(sqrt(y)) = sqrt(x + y).
Square both sides we get (x2)(y) = x + y.
Subtract y from both sides (x2)(y) - y = x.
Factor the left side (y)(x2 - 1) = x.
Finally, divide y = x/(x2 - 1).

So you can pick any whole number value of x -- 2, 3, 10, whatever -- and substitute on the right side. You will get a value of y which is the fractional part of the mixed number that makes the "strange" square root work.

On a historical note: This is comic #1066. If you thought I'd do something about The Battle of Hastings ... well, it had crossed my mind, but too complicated and no way to plan in advance with the crazy schedule I'm keeping.

### Happy Thanksgiving 2015

(Click on the comic if you can't see the full image.)

It's actually 3 1/8 pecans because cutting 1/7 of a pecan is as impossible as cutting .141592... pecans.

Actually, it's more likely that a pecan was split in half and then cut four more times to make 8 pieces, but they wouldn't exactly be actually pieces of eight.

Happy Thanksgiving to you and yours!

The second verse would've had a line like ''if you look you can find me by the symmet-tree!'' in the Big Quadratic Mountain.

This is an old song that dates back to the 1800s. However, the first version I'd encountered was a sanitized version that was turned into a children's tune for one of a series of kiddie videos about 20 years ago. (The videos were a little older than that.)

The next encounter I had was finding out that Burl Ives had recorded a version of the song. But for all his friendly Rudolph cheer, his was the traditional rendition, not one aimed at the kids.

### Veterans Day 2015

(Click on the comic if you can't see the full image.)

I admit: I was tapped out this year. I've thanked people and made puns, and there wasn't else I could say, except "Thank You" again. I have no problems with the Thank You's, but it doesn't make for a good comic, especially when I haven't updated in a week (because of work and other concerns).

Earlier this morning, while I was sweeping a mess of leaves outside, this came to me. I realize that I've seen an Internet "joke" with something similar on a test paper, but I still put my own little twist on it. For one thing, I got to bring out the (Grand)father and (Great)Uncle characters. For another, I added a little diversity to the mix of character -- something I've been reluctant to do because I was afraid it would turn out badly.

My last regret about doing this last minute: I don't have the numbers and the diversity I would like in this pic. But any more people and they would have been blurs in the background. After 1000 comics, my skill is improving, but I have a long way to go. And I still have my day job.

Happy Veterans Day.

Ba Na Na Na Na!

Halloween comics are over, and with work keeping my busy, I managed -- not for the first time -- forget our anniversary, which was a week ago on October 24.

(x, why?) is EIGHT YEARS OLD, and already into it's Ninth Year. It that time, I've produced over 1,000 comics, many bad puns, many worse puns, and many song parodies. I've created characters with no names and made them into pieces of me.

And I've managed to be seen around the world (according to my stats), and I've had comics reposted by Math Councils and translated into foreign languages for universities.

It's been good. Let's keep it going.

### Happy Back to the Future Day!

(Click on the comic if you can't see the full image.)

Really, why do you need to kill his grandfather when you only have to kill the mood with some annoying, badly-timed phone calls and interruptions. Smaller chance of going to prison, and it leaves out the whole murder thing -- although whether or not knowingly preventing a known conception from occurring is akin to the murder of a future individual should be left to the philosophers.

As for the movie trilogy timeline, time travel is one of those devices which can be handled in a thousand different ways. As long as a story is internally consistent. The argument ensues from the fact that many viewers don't think Back to the Future is actually consistent. The Rules are what the Rules Need To Be at whatever point the script calls for them to be that.

Last two notes: since my early days on social media, I have been seeing Photoshops of the DeLorean's dashboard clock saying "today is the day Marty McFly landed in the future" -- and in every instance, it has been wrong. Oddly, I haven't seen it posted recently.

Secondly, as of tomorrow, Back to the Future is a time travel movie that takes place totally in the Past. This is actually a cool sub-genre of movies, watching a past time portrayed as future events extrapolated from some either further point in time. Cheesy results, sometimes, but cool.

### (x, why?) Mini: Covalent

(Click on the comic if you can't see the full image.)

"'ey! You! What's with the finger?"

The "dihydrogen monoxide" was supposed to be the alt text, but I figured I'd add it for that little extra.
It was almost just "dihydrogen oxide" because I wasn't sure what would fit in the word ballon.

I also could've jettisoned that pun altogether and went for Gold Oxide, Au2O3, which would've added Au to the mix, but then I would have had to have started with ozone, O3, instead.

Well, I guess I could've done that, but O2 is more common.

### Eclipse

(Click on the comic if you can't see the full image.)

So guess what I was doing on Sunday night!

Yes, I have an old telescope, which rarely gets used, and I was set up trying to align it with the Moon and NOT move it when I tried to put the tablet camera up against the lens. And, of course, I had to wait for the large clouds to move out of the way, by which point, I had to reposition the telescope.

Actually, I had to physically move it. Between trees and neighboring buildings, I had to shift it in the driveway. By the time the Moon was red, I would have had to have put the telescope in one specific spot at the other side of the house. However, by that point, I'd already put it back in the basement, so no Blood Moon pics. Seriously, I had enough just getting what you saw, and I got those by accident. By mistake, I took video. Those are three still images from the video I shot.
