And sharing the screen.

There we go.

So welcome everybody to today's lab session.

We'll start by looking at the homeworks remember we were in the last.

In the last smart phone connected.

We were talking about.

Proofs.

The type of our proofs of a certain.

Applicate proposition.

The, let me just scroll to the.

To the right place.

So far.

There we go.

Looking at actions, actions.

Being decorations of.

Terms that have a certain proof type.

And us saying this proposition is probable.

Again, by fiat.

Because we have the power to do so.

But there's a risk involved whenever we declare axioms.

There's a risk that we introduce inconsistently.

We don't like to do this. We'd rather do theorems.

And.

Theorems are constructed.

By centrally proof constructors.

And we've looked at one.

On your homework.

Was to build more.

So.

Let's look at your homeworks.

Means I should.

Stop sharing.

And give the share to Frederick.

Any volunteers about whose homework we should.

Just mean was first.

No, you're first.

We have to select something.

One criteria.

If you don't really want to.

Okay.

So.

Last time.

I should probably get out of the way here.

Right.

This looks like wonderful.

As it should.

I think it's a good idea.

I didn't know.

I saw the best thing.

I just couldn't.
