Then you wanna do multiplication... multiplication and division, and then finally you do addition and subtraction.

We have some division going on here, and a multiplication there.

So the next thing we should do... There are no exponents. The next thing is multiplication.

But she had this great quote talking about no one believing that she could do such a thing, and they told her that computers could only do arithmetic.

They are in projection you asked for, General.

That this is the same thing as the log base 10 of 3, divided by the log base 10 of 7.

So we should do these next, before we do this addition right there.

This is a very short notation for squaring it.

So, to some extents, it's tedious to compute these values, but they can be perfectly computed, as shown here.

We try to evaluate what category that

What do i mean by that?

See I do this in real time.

And the missing 1 5 shows up over here.

And we're left with minus 5 minus 31 4.

Now, with a surprising increase in difficulty

And if we could calculate the allowed vibrational patterns, we should be able to calculate those 20 numbers.

For the main diagonal elements you get the same formula as before.

And so this is the same thing as 10 100.

Nowadays, we test the speed of computers by having them calculate pi, and quantum computers have been able to calculate it up to two quadrillion digits.

He doesn't check his figures when he's calculating.

Any style yeah, good.

Calculate simple sums

So this is going to be 7 plus and the 3 times 3 we want to do first.

Can you compute the distance of the moon from the earth?

The most important applications in those days were scientific computations, and programmers thought in terms of writing down formulas in a form that the machine could execute.

You know, I've realized that Wolfram Alpha actually gives one a whole new kind of computing that one can call knowledge based computing, in which one's starting not just from raw computation, but from a vast amount of built in knowledge.

We got minus 2 over 3.

So you can actually kind of do them simultaneously.

Because we can actually figure out every asteroid that's out there, and if it might hit Earth, and when it might hit Earth.

leaving us with the total of 7 elements.

These are trajectories going to Mars.

The first recorded computer calculation of Pi was done by a man named Ferguson on a desk calculator in 1947.

So this right over here is the numerical expression that models the situation without any, without performing any operations.

So notice we interpreted this statement in two different ways this was just straight left to right, doing the addition, then the multiplication.

We could do this by hand, but let me just get the calculator out to make things move along a little bit faster.

You won't multiply by 4 divided by 2.

So there's all sorts of crazy things here, but if you just follow the Order of Operations, you'll simplify it in a very clean way and hopefully we'll all get the same answer.

Any computation I could carry out in Python I could also carry out in JavaScript.

So you could say well, let me just take 7 3.

If only there were some way I could carryout this computation on my webpage.

Now, once we've invoked our multiplication algorithm recursively four times to compute these four relevant products.

They are not together.

That's just this first column, OK?

When we print out the first print, a is 2.

And so, I'll multiply by 0.454 divided by 0.0254 squared.
