Imagine we are living in prehistoric times.

Thing looks prehistoric.

like a prehistoric scientist.

The prehistoric origin of the vampire myth.

They look positively prehistoric and a bit scary.

But the most intriguing prehistoric artifacts are older even than this.

Someone is re engineering dinosaurs by extracting their DNA from prehistoric amber.

This seems prehistoric now, but this was where we were with technology.

I bet those prehistoric cave artists would have loved to know how to draw better.

Here, in addition to fossils, we have genetics to help us find our prehistoric kin.

9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1.

Then times 5 times 4 times 3 times 2 times 1.

Ten times 10, times 10, times 10, times 10, times 10...

We have two times two times two, times, two times two times two times two times two.

This should be 9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1.

She was tasked with travelling through time, fighting prehistoric monsters with her magical staff and saving the world.

I like to think of each series as the trunk of a tree, where I took you from prehistoric times to around the 20th century, which is here, with a few different threads.

So it was 7 times 6 times 5 times 4 times 3 times 2 times 1.

Two times nine times ten times one hundred times one thousand times one million.

Seven times seven times seven times seven.

4 times 3 times 2 times 1.

So times is , times AC times BD

4 times 3 times 2 times 1.

And that's two times two times two times two times two.

So it would be .8 times .2 times .8 times .2 times .8 times .8.

Times c, times 3.

Times well what times?

Good times. Bad times.

That's .5 times .5 times .5 times .5.

If this was just 3 was so 7 times 6 times 5 times 4 times 3 times 2 times 1.

To understand this whole thing better we need to go way back in time, to say, like, the prehistoric age.

Well, that would just be equal to 4 times 5 times 4 times 5 times 4 times 5, right, which is the same thing as 4 times 4 times 4 times 5 times 5 times 5, right?

And then we have 32 times 31 times 30 times 29 times 28.

So, times zero, times zero.

3 times 6 times 10.

4 times 8 times 42.

length times x times 9.

8 times 8 times 8

four y x. two times two times y times x.

Two times x, two times x, and two times x.

Well that means 2 times 2 times 2 times 2.

Instead of multiplying 4 times y times 2 times y,

Times 15 times .8 to the fourth, times .2 squared.

Times

A to the fifth literally means a times a times a times a times a.
