I think he is unrealistic in thinking that his ideas can be implimented by usa elections.

Let me try to take this one step further. Laughter I'm going to try to square a four-digit number this time.

You can all take your time on this; I will not beat you to the answer on this one, but I will try to get the answer right.

To make this a little bit more random, let's take the fourth row this time, let's say, one, two, three, four.

If each of you would call out a single digit between zero and nine, that will be the four-digit number that I'll square. Thank you very much.

Applause Applause ends Now, I would attempt to square a five-digit number — and I can — but unfortunately, most calculators cannot. Laughter Eight-digit capacity — don't you hate that? So, since we've reached the limits of our calculators — what's that? Does yours go higher? I can probably do it.

I'll talk to you later. In the meanwhile, let me conclude the first part of my show by doing something a little trickier.

Let's take the largest number on the board here, Would you each enter that on your calculator? And instead of squaring it this time, I want you to take that number and multiply it by any three-digit number that you want, but don't tell me what you're multiplying by — just multiply it by any random three-digit number.

So you should have as an answer either a six-digit or probably a seven-digit number. How many digits do you have, six or seven?

Is there any possible way that I could know what seven-digit numbers you have? What I'd like each of you to do is to call out for me any six of your seven digits, any six of them, in any order you'd like. Laughter One digit at a time, I shall try and determine the digit you've left out.

Starting with your seven-digit number, call out any six of them please.

Did you leave out the number 6? Good, OK, that's one. You have a seven-digit number, call out any six of them please. I think I only heard five numbers.

I — wait — — did you leave out the number 6? Same as she did, OK.

You've got a seven-digit number — call out any six of them loud and clear. I think you left out the number 3? The odds of me getting all four of these right by random guessing would be one in 10,Practical Homeschooling Articles / Columnists 1,+ free articles on how to homeschool, college at home, math, science, history, reading, unit studies, classical education, much more!

Arthur Benjamin: Lightning Calculation and Other “Mathemagic” Posted by Dave Richeson on April 18, I’m continuing to enjoy watching mathematics videos online.

Watch these TED Talks to learn how math is not only magical, but incredibly necessary: Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities -- that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population.

In this mind-bending talk from TEDGlobal he shows how it works and how similar . The Stranger Beside Me has 46, ratings and 2, reviews. Jeffrey said: “And, like all the others, I have been manipulated to suit Ted’s needs. I don’.
