We have made a square.

Every square is a rectangle.

Patient A square and a circle.

Tom drew a large square.

57,683 squared. Yuck.

It's a square, not a cube.

The square of this distance should be exponentially distributed with a certain mean.

Squaring Asia s Nuclear Triangle

And previously we did the square.

The square of the hypotenuse is equal to the sum of the squares of the other two sides.

This square might look very square and prim.

The square of any prime number is a semiprime.

A square is a shape with four sides of equal length and ninety degree corners.

In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90 degree angles, or right angles).

We are going to build a bigger size square around this small square.

A square is always a rectangle, but a rectangle is not always a square.

The solution to the quadrilateral isoperimetric problem is the square, and the solution to the triangle problem is the equilateral triangle.

OK, what I'm going to try and do, is to square in my head a five digit number requiring a 10 digit calculator.

You have a very sensitive computer program where small changes single, tiny, little mutations can take something that made one size square and make something very much bigger.

Here is a particular example, the derivative of the squaring function at the input 3.

Pythagoras' theorem says that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Call out a single digit that will be the five digit number that I will try to square. Go ahead.

So, it goes from a circle, to a round, to a square, to a figure eight.

As you can see, we make the bigger square working our way around the small, center square.

AB 25. Now, the way we can square on most calculators let me demonstrate with this one is by taking the number, such as five, hitting times and then equals, and on most calculators that will give you the square.

Well if 100, if we think of 100 as being like a square, 75 would look like this.

A square is a quadrilateral with four sides the same and where all four corners are right angles.

What I'm going to try and do now is to square, in my head, four two digit numbers faster than they can do on their calculators, even using the shortcut method.

Here's the DNA origami, and what we can do is we can write 32 on both edges of the DNA origami, and we can now use our watering can and water with tiles, and we can start growing tiles off of that and create a square.

Pepperberg can show Alex two objects (for example, a green square and a red square) and ask, What's different?

And if you do that, the origami's the same size, but the resulting square that you get is three times bigger.

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.

It's the same basic game except I introduced a new piece, a square piece that can move both horizontally and vertically.

Now, I would attempt to square a five digit number and I can but unfortunately most calculators cannot.

Zoom in and that square thing is a theater which we're in right now The Terrace Theater. It didn't have a name on it.

By averaging the squared difference between each value and the mean and finding the square root of the result, we can find the standard deviation.

The walls were plastered with imitation marble and the enormous plate glass windows were already in place only the parquet floor was not finished, and the carpenters who were planing a square of the parquet left their work, and removing the tapes that kept their hair out of the way, bowed to the gentlefolk.

In a lively show, mathemagician Arthur Benjamin races a team of calculators to figure out 3 digit squares, solves another massive mental equation and guesses a few birthdays. How does he do it? He ll tell you.

Take a square. Fold it in half, fold it in half, fold it again, until it gets long and narrow, and then we'll say at the end of that, that's a flap.

So this is going to be equal to the limit as x approaches infinity of 4 minus 5 over x over 1 over x squared minus 3.

What I'll use is the second row this time, and I'll get four of you one, two, three, four to each yell out a two digit number, and if you would square the first number, and if you would square the second, the third and the fourth, I will try and race you to the answer. OK?

If so, they would take a step in the Singapore direction and reduce if not endanger the third element of a program of squaring the circle, that of doing it all in a free society.

So they pick a shape they like like a diamond, or a square, or a triangle, or a trapezoid and then they try and make the next larger shape of that same shape, and the next larger shape.

If you look at the square that you build with the origami and some counters growing off it, the pattern that it has is exactly the pattern that you need to make a memory.

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.
