Ones place, tens place, hundreds place, thousands place, ten thousands place.

It's in the tens place.

It's the place that's called the tens place.

Then you go the tens place.

Now we're in the tens place.

And the 3 is in the tens place, so it's 3 tens.

And this place right here is called the tens place.

But notice, we're in the tens place.

So that's what the tens place is.

And then we add the tens place.

And now it's in the tens place.

And the tens place is essentially telling you how many that's the tens.

Now why is it called the tens place?

So I write 2 in the tens place.

And now we focus on the tens place.

This is a two in the tens place.

This was the ones place, the tens place, now we're in the hundreds place.

Well, I wanted to separate the ones place from the tens place.

So I add up everything in the tens place.

So we want to focus on the tens place.

So we put the three in the tens place.

In this case, it's not the ones place, the tens place, the hundreds place, and the thousands place.

Well, let's take a 10 from the tens place. We're going to regroup. So we're going to get rid of one of these tens, so we're only going to have 6 tens left in the tens place.

A 2 in the tens place means two 10 bills.

And let me give that 100 to my tens place.

So let's write that one 10 in the tens place.

So if you take that hundred and give it to the tens place, a hundred is 10 tens.

The fact that it's in the tens place represents or the fact that the 4 is in the tens place shows that it represents 40.

In this case we have a 0 in the tens place.

So we put that one up there in the tens place.

Tens.

I can just look at each place, the ones place and subtract, tens places and subtract.

Now we can multiply this five, which is in the tens place.

Well, we put it in the tens place... one 10 represents 10.

We can write the 5 in the ones place and carry the 4 to the tens place.

This right here, the 7, is in the ones place. The 9 is in the tens place.

So we took a hundred from the hundreds place, and we could give it to the tens place.

We put the six, the five, and the eight in the tens place.

Remember, if I borrow 1 from the tens place, that's actually a 10.

And then in the tens place we just have this two sitting here.

And when I re wrote the 100 in the tens place, it's ten 10s.

Put the two up here in the tens place, because it's twenty plus seven.

Well, since that four is in the tens place, we add a zero here.

If you have let's say a number we write out 451 we consider this the ones place, the tens place, and the hundreds place.

So this 9 is in the hundreds place, so it represents 900. The 7 is in the tens place, so it represents 7 tens. And then, this 1 is in the ones place, so it just represents 1.
