We don't have to wait until the end of the problem.

Number of fixed decimal digits

Number of fixed decimal digits.

Then you count the decimal spots. one, two.

So now we have everything lined up.

And, since we're going to go into the places less than the ones place we're gonna go into the tenths place and the hundredths place and the thousandths place,

So every time you multiply something by 10, you're shifting the decimal over to the right once.

And you get six zero zero.

If it's a one, I'll make mine a two otherwise I'll make mine a one.

I'll construct my decimal one place at a time.

It don't know, there something wacky about that that the inverse of the number is really just the decimals

Everything that's in the ones place is below or above everything else in the ones place.

Then we have the 7. Let me do that in another color.

These two elements over here are called the lower quartile and guess what the upper quartile.

And you see, every time you move to the left, you move one place to the left, you're multiplying by 10.

So we can rewrite this as 5.005 divided by 7.

Whether to use fixed decimal places

Whether to use fixed decimal places.

I want to write this in scientific notation, so I take the leading digit, 1, put a decimal sign.

You don't know how to do it, but let me tell you.

Is the covariance large, medium, or small?

This is just written a little bit higher

Or you can just do the technique where you move the decimal space over two to the left.

I read it to the negative 1 power

So let's clean this up a little bit so we remember what we did.

You clearly do not have a zero in the ones place here.

And this will be a 15 from reads 19, 23.

Does 2 go into 75?

Shift it two to the right.

Let me put that in a new color.

For example, factoring quadratics with

You would say, Look!

Let's go over this very quickly.

left, and you would have to add another 0.

Express the rational number 19 27 (or 19 27ths) as a terminating decimal or a decimal that eventually repeats.

So, we're going to get a value less than 1.

We happen to know that the projection of p on the two image planes is somewhat different.

Every time you multiply it by 10, you shift the decimal to the right by 1.

What we do here is we just first look at the ones place

So really what we're saying is 518 divided by 0.7 is the same thing as 5,180 divided by divided by 7.

So this we rewrite as (let me use that same green color) 373 plus... we want to write the ones under the ones place, and the tens place under the tens place, so that we're adding the appropriate values.

So what you do is you always want to take this decimal and move it over as many spaces as necessary to turn this number into a whole number.

The minus sign can only occur at the beginning, and it's also optional.

I've named them like that so I don't forget which way around they are.

So now let's get some concrete practice coding this up in Python.
