A simple calculator for chemistry

This and this is the same number so that's why those cancel out.

Now we just have to do some math, calculate these things.

And so what does that turn out to be?

And then all of this on the left hand side

So let's figure out what that actually is.

The calculator on the table is mine.

So I'm guessing it gonna be 1. something something.

I can do the math as long as I have a calculator.

So, let's think about it this way

To actually solve it, to get the exact answer, is not an easy thing to do.

That's going on no matter what anybody thinks.

Let's see.

And we'll talk about things like inverses in the future that are symmetric around the line, y is equal to x.

If this sounds foreign to you, please note that if you have ever used a calculator you have delegated your decision making to a machine.

I've had my pocket calculator stolen.

Various desktop tools like a calculator, an editor and other nifty stuff.

And that is just a number.

Let me do them by hand because I think that's instructive sometimes before you take out the graphing calculator.

We'll experiment a little bit with a graphing calculator in a few videos.

Now, we have to figure out what that is.

(Laughter)

Does yours go higher?

And if you want their actual values, you can get your calculator out.

It'd be velocity if we also specified the direction.

(Applause)

So we'd say 0.6 times 150 and then we'd say plus 0.4 times 180, and that gets us to, let me get my calculator out, so that gets us 0.6 times 150 plus 0.4 times 180.

Let me write that down, 0.995.

Let's take the largest number on the board here, 8649.

The answer is about 300 290.6.

And we can figure out what that is. Let me get a calculator out.

Obviously, these are the numbers with which to compute the mean.

OK, over there on the aisle.

Eight digit capacity don't you hate that?

To the table tennis table Pia, we're in the common room

And let me do that, because I think that will be interesting. So let me get a calculator out...

So what is the logorithm? Well, for our purposes, we can just think of a logorithm as follows, okay?

So what does that turn out to on a per job basis?

We could work it out.

Using the old thinking, of national infrastructure and pipe work, is too expensive.
