But it's a very powerful technique.

You can actually look at the formula.

And just so you know, I don't know if you're familiar with Excel.

(Applause)

I do all those things on Poisson processes and things like that.

If I want to take the transpose of a matrix that's just converting columns into rows.

It's an Excel spreadsheet.

I e mailed an application, what was sent to back me was an Excel template for CV.

So that equals 1,000e to the 0.75 power, and let me calculate what that is in Excel.

You can download it at khanacademy.org downloads buyrent.xls.

It becomes 1.027 to the 365th power.

And if I charged you 2.7 every day, but I compound it for 365 days, it becomes I'm just using Excel here.

So one sort of tricky thing about R , especially for people who are coming from a different software package like SPSS or, or SAS or even something simple li ke

They're making some assumption about the discount rates.

They told me that just a few people sent their CVs back because they didn't have Excel skills.

Let me just squeeze this a little bit.

Everything here is in the negative, right, according to the legend, minus 50 to zero percent return.

And you are essentially discounting them back to get today's present value.

In Excel, the e to the power so I wrote that it's a 1,000 times e to a power in Excel is exp.

But I could create an Excel CV, and sent it back, because I had some interests in computers and did buy one, playing with Word and Excel when I was a housewife.

And so if you download this model and want to play with it yourself, unless you are fairly sophisticated with

But this is a major investment that I'm thinking about making, so at minimum, I made a spreadsheet here in Excel and it's available at khanacademy.org downloads cupcakes.xls.

The first thing we're going to do in a script, and this is true of every script you'll write this semester is you'll read the data into what's called a data frame.

And after a full year, you'll actually owe me 1.085 to the 12th power, and let's see what that is.

Ah Oppa!

It's so close! Right?! Right?!

But the general theme here is, when you're at high utilization the whole reason why I'm even entering into this whole spreadsheet and all of that, is to talk about inflation in general.

So we tried to come up with a non tracking collector that would gather much more than one degree of light, with no moving parts.

There's actually a ton of scenarios because you can keep adjusting how much you sell and the price you sell it for and come up with different numbers here.

This leaves local residents to deal with the thousands of spontaneous volunteers, thousands of donations, and all with no training and no tools.

Ah, Teach, you can tell by your temples.

Dish it out!

Where, where?

And since I've already gone down this compound interest track, let's just keep going so that I can put these videos in both my mathematics and my finance playlists.

Where? Where
