I haven't shown this to you yet.

Braces

The Parentheses around option displays the numeric value within a pair of parentheses.

So just remember, the top priority is always going to be your parentheses.

Parentheses Around

Close parenthesis

If I were to change this a bit. I've been very minorly devious.

Unbalanced right parenthesis

We didn't really remember where we'd come from.

We could also look at it like this.

AutoBrace

But 6x minus x is 5x.

We're going to define a procedure, so we use the def followed by the name.

Let's say I type max A and then this will be it.

I factored it out of both of these guys.

Missing parenthesis

Missing right parenthesis

You have that 5.

This is 4 y squared.

So let's try a few examples. So we'll create a dictionary.

There could be one input.

Here, we're not including 10 3.

Let's see if we can simplify this a little bit.

So that one wasn't too bad.

You would just have to follow the order of operations.

And so now, we just simplify this.

That's an identifier, like myfun , followed by a Left parenthesis, followed by some optional arguments, followed by a Right parenthesis.

I can rewrite this up here as 2x squared plus 2x plus 3x plus 3, just like that.

You're never at infinity.

Way up at the top of this file, I've defined a particular grammar.

Negative 1 times 3 is negative 3.

Although again, if it's a single line, you don't require those braces to be there.

Let's do twox plus y.

All the way to infinity

And now is fun part.

Anything that we could use as a variable, we can use as the name of a procedure.

Python not so much.

Higher precedence means it gets done first.

There's an identifier. That's the name of the function.

So you have your parentheses Let me write it this way.

Let's see what this give us.

But that's what parentheses help us do.
