The more I talk to people about math, the more I realize this on simple fact: Math ability hinges on confidence. If you think you can do it, you can. And even though I don’t know you at all, I know for sure that you can do math. Promise. Check out the video for details.

Math is black-and-white, all about right and wrong answers. Right? Well, not really. In fact, math is a lot more like writing than hitting on the correct answers. Turns out, focusing on the concepts might just help you learn to like math a little more! Check out the video for details.

If you’ve ever been stuck in a grocery store wondering if you have enough cash in your pocket to cover what you need, you’re probably pretty familiar with the power of estimation. In this video, I show you how to estimate and why it’s such a big deal.

Oh, the math competitions! From speed math to scrambling to get the correct answer, competing with math can be a very bad idea. In this video, I talk about when competition and math are a bad mix. Take a look!

What’s the best way to learn new math ideas? The answer might surprise you. But like learning a foreign language or that the little brake light on your dashboard means get to the mechanic — now! — getting the hang of math may require a little bit of discovery, rather than listening to boring lectures or reading books. And getting your Christopher Columbus on means failing a few times too. Here’s how discovery and failure play an important role in math education.

If your hands get sweaty, heart starts to race and your brain shuts down at the thought of doing math, you might have math anxiety. This is a very real condition with very real consequences — from making more mistakes to avoiding math altogether.

But there’s really great news. You can get over math anxiety. And, if you have kids, you can help them avoid getting it in the first place. This video shares a few tips. And if you want more, sign up for my free resource, Multiply Your Math Moxie: A Painless Guide to Overcoming Math Anxiety. Check out the yellow box to the right!

I never was fond of the step-by-step process many of my math teachers favored. But by the time I reached high school, I figured out that math is pretty darned flexible. And in college, that lesson really took hold.

You may think that math is black and white, but honestly? There are many different ways to solve simple and complex math problems. And that’s what I explain in my latest video. Check out how you can be creative with your math solutions — and still arrive at the correct answer!

By now, most of us know that girls have great math skills. Still, there are some folks out there who are holding on to the bias that boys naturally have better math abilities than girls.

In my latest Math Manifesto video, I go through some of the recent research on gender and math. It’s good news for girls and boys!

As always, I’d love to hear what you think. Ask your questions or share your feedback in the comments section. After watching the video, are you convinced — as I am — that both girls and boys have math brains? Why or why not? And to all of you grownup girls, how has your gender affected your affected your math learning and doing? Did you ever buy in to the idea that you could not do math as well as your brothers, father, husband or male classmates? I would love to hear your stories!

Think you don’t need math? Think again! Math is everywhere, and much of the time you might not even realize that you’re doing it.

If you remember wondering when you’d ever use math as a grownup, click on my next Math Manifesto video above.

As I announced earlier this week, I’m retiring Film Friday.  While I had a lot of fun looking for videos to share with you, the posts didn’t get a lot of traffic.  Remembering that insanity is doing the same thing over and over again while expecting different results, I’ve decided to get off this merry-go-round.

That doesn’t mean I’ll never include videos again.  In fact, I’d like to do video posts where I’m actually on screen to teach you a few things.  But for now, I’m taking a different route.  (Get the details here.)

So for today, we bid adieu to Film Friday here at Math for Grownups.  And as a parting gift, I share my favorite videos with you!

This video is so gorgeous.  I could watch it over and over again. (And I have.)

Ursus Wehrli is both infuriatingly precise and hilarious.

Do you remember the difference between the deficit and the debt ceiling?

I LOVE this guy.  He’s the fellow who produced Facebook for Math Nerds and Twitter for Math Nerds. And in honor of Steve Jobs, I thought I’d post his latest video today.  It’s all in good fun, but think about it: If you couldn’t read a simple bar graph, Venn Diagram or line graph, it wouldn’t mean a thing to you.

In her quest to convince me that math is a stupid subject, my daughter started playing a little game with me last year.  She really thought she could come up with something that doesn’t have to do with math.  For a couple of days, she shouted words at me — like “flowers,” “air,” “water,” “running” — and I easily explained how math was important in each one.

That’s when we first started talking about the Fibonacci Sequence, which is nothing more than a sequence of numbers that go on forever and ever: 1, 1, 2, 3, 5, 8, 13, 21, … If you look at the sequence carefully, you can guess what the next numbers are.  But did you know that the Fibonacci Sequence is found everywhere in nature?

This video is a really cool look at this phenomenon, as well as other applications of math in nature.  And you don’t need to understand the math to appreciate the beauty.  Just take a look and enjoy.
