Friday math movie: A clever way to estimate enormous numbers

By Murray Bourne, 06 Sep 2013

It's important to be able to make estimates before attempting problems. Very few students get practice at this important math skill.

In this video, Michael Mitchell begins with an overview of scientific notation and goes on to give us some suggestions on using powers of 10 to estimate large numbers.

See the associated TED-Ed lesson that goes with this video.

The video is one of the highly recommended 8 Math Talks to Blow Your Mind by TED.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can't mix both types of math entry in your comment.
