# How To Enter Burning Questions Round 6.5

People search for stuff at Instructables all the time. Sometimes they find what they're looking for, and sometimes they don't. But there are a few common how-tos that come up often enough that make us wonder, "why don't we have an Instructable on that?"

The answer is because no one has written one. But you can change all that.

In round six of burning questions we got great info on "How to Divide" and "How to factor." Now as good as those two instructables were, it made us realize that there's a whole lot more math how-to's that we'd left out.

In an effort to start with the basics, below is a list of "wanted Instructables". Write an Instructable about one of these topics and you will be eligible to win an Instructables Burning Questions Prize Pack consisting of an instructables robot t-shirt, a robot patch and a Burning Questions bumper sticker! Plus, one winner will receive a TI-30XS Multiview Calculator.

Be sure to provide a great Instructable and give it the same title as it appears in the list. Please read the full requirements below before entering.

Wanted Instructables:
• How to Subtract
• How to Multiply
• Subtracting Fractions
• Dividing Fractions
• Multiplying Fractions
• Decimal to Fraction
• How to Graph
• Multiplication Tables
• Area of a Circle
• Area of a Cylinder
• Volume of a Sphere
• Volume of a Cylinder
• Surface Area of a Sphere
• Circumference of a Circle

• Rules:
- The Instructables have to be of very good quality. So include well written text, plenty of details, original pictures, and provide a thorough answer to the question. If they're lousy (you know when they are), your project won't be allowed into the contest.
- The Instructables have to include their own original images taken by you, the author. Instructables comprised of images found online will not be allowed into the group. There are many applications you can find that will help you make equations, DragMath, Open Office Math Editor, MathCast, LaTeXiT, and a slew of others should ensure your instructable is as easy as possible for others to follow.
- They have to be titled exactly as they appear above. Why? Because that's what people are looking for.
- They have to have a publish date after 2009-01-27.
- They have to be on the list! Only Instructables answering questions on the list will be admitted to the group.

If multiple users decide to answer the same question, we'll pick the Instructable that answers the question best and declare them the winner. So make sure that your answer is the best it can possibly be!

That's it, so go forth and hunt down the answers for some of these Burning Questions! Once again, the title needs to be the same as it is in the list!

Prizes:
Grand Prize: Winner who best answers a question from the "Wanted Instructables" list will receive a a TI-30XS Multiview Calculator, an Instructables robot t-shirt and a Burning Questions prize pack consisting of a Burning Questions bumper sticker and a robot patch.
Value: \$50

First Prize: Winners who answer questions from the "Wanted Instructables" list will receive an Instructables robot t-shirt and a Burning Questions prize pack consisting of a Burning Questions bumper sticker and a robot patch.
Value: \$30

I'm offended by your lack of tolerance - it looks nothing like a cross.
Plasmana in reply to robots1994 years ago
It looks nothing like a cross, it looks like a plus.
DavidRobertson in reply to robots1994 years ago
Oh for goodness sake its obviously a plus sign. If there was nothing in the world that was offensive to someone in some remote way then there would be nothing in the world!

Can you post a video?
Burning Questions (author) in reply to amakerguy4 years ago
You can do a typical step by step instructable, a slideshow or a video. Anything you want to upload is fine. So long as your not in breach of the rules, it will be approved. If the community decides that your project is best at describing what it is you set out to explain, you will win the prize for that category.
StumpChunkman in reply to amakerguy4 years ago
Absolutely. I'd be interested to see how you put that together.
amakerguy in reply to StumpChunkman4 years ago
yeah but are you the staff?
zachninme says: 4 years ago
What about using a slide rule? I just found one 3 days ago and figured out how to use it. I'm thinking about whipping it out on the next math test...
StumpChunkman in reply to zachninme4 years ago
While not part of this contest, I'd actually be quite interested in seeing an instructable on how to use a slide rule. Not a talent most people just have, and if I ever happen across one in my random travels, it'd be fun to show off a somewhat random skill that I probably don't need.

The contest isn't appearing in the contest panel I know its up i just have to take a round about way of finding it :0
Phoenixsong says: 4 years ago
I'm going to do the How to Graph one.

Anybody doing adding fractions? hope not, i'm almost done.
ggiihh1 says: 4 years ago
A) can we enter more than 1 instructable?? (i know it's usually you can enter as many as you want but you can only win once, but it doesn't say anything in the rules for this)
B) How long does it usually take for a instructable to be reviewed? (i already entered 1 for decimal to fraction)
noahw in reply to ggiihh14 years ago
A) You can answer as many burning questions as you like. If you have the winning answer to more than one question, we'll give you multiple prizes. Go for it!

B) It can take a few minutes or up to a day for a project to be reviewed - it all depends on the contest moderator. Don't worry if it doesn't show up immediately, it will be reviewed (it's not me this time!).
Ummm, the burning plus sign kinda looks like a burning cross. Might be an unintentional faux pas from the graphics dept approved by the marketing dept...
Sometimes a burning plus sign is just a burning plus sign. I looked at the same picture and saw mathematical symbols that look like they are on fire - a clever design for the name of the contest!
True, and nothing wrong in its proper context. But you know the conspiracy folks lurking out there...
The arms of the plus sign are equal in length and intersect at their centers. With a cross the horizontal arm tends to be shorter and it intersects about 2/3 of the way up on the vertical. I think most folks will see a plus sign unless they glance very quickly. And then they'll probably look a little more closely and realize it's a plus sign. I think you hit the nail on the head when you said "context". In this instance since the symbol in question is not surrounded by racial epithets or other language that indicates it is being used in a hateful way. I don't think most people would be offended by it. And if they are well the first amendment protects speech so they'll just have to deal with it.
I'll just call it an observation on graphic arts. Art and design in whatever form should evoke a feeling, good and bad. So drawing on my own life experiences, this is what came across my mind. I would be the first to defend the artist but in today's polically correct world, a figure intentionally "torching" something semi-remotely resembling something sacred and the symbolism that goes with it quite strong. The majority of us can rationalize there was no harm or foul intended but there will always be one more sensitve and think the contrary seeing something different.

I AM SO ENTERING THIS CONTEST IM GOING TO DO THEM ALL I'M A MATH GENIUS BTW :D !!!
ggiihh1 says: 4 years ago
i call decimal to fraction. i'm almost done. =]
perlpower says: 4 years ago
I thought of one that I would like to do, however it is not on the list. I'll probably do it anyways, but would it be okay to submit it to the contest? The topic that I would do is calculating square roots.
StumpChunkman in reply to perlpower4 years ago
That sounds fantastic, but according to the rules, only "wanted instructables" will be allowed into the contest.
meh301 in reply to StumpChunkman4 years ago
calculating square roots is wanted by me!
dchall8 says: 4 years ago
It's going back a ways but isn't the volume of a sphere simply the triple integral of the distance from the center to the edge for the special case where the distance is the same in all three dimensions? You need a whole Instructable for that? Just kidding. I don't know why that unhelpful bit of info came to mind.
Chicken2209 says: 4 years ago
how to add? how to subtract? wow these are easy ibles... i thought most 13+ year old kids would know most of this but maybe I can turn how to graph into something a little more extreme
Weissensteinburg in reply to Chicken22094 years ago
Adding and subtracting can also include tricks for large and very large numbers, as well as for doing mental math.
