We are given five expressions to evaluate **on sight**, just by looking at them and mulling them over in our mind.

Set bool_one equal to the result of

```
False or not True and True
```

Set bool_two equal to the result of

```
False and not True or True
```

Set bool_three equal to the result of

```
True and not (False or False)
```

Set bool_four equal to the result of

```
not not True or False and not True
```

Set bool_five equal to the result of

```
False or not (True and True)
```

In the editor pane, type the boolean that applies to each.

```
bool_one =
bool_two =
bool_three =
bool_four =
bool_five =
```

Let’s look at the first one and evaluate it only in terms of precedence…

```
False or not True and True
```

- Any
`not`

's?
- Any
`and`

's?
- Any
`or`

's?

So evlauate `not True`

, first. => False. Now recompose,

```
False or False and True
```

Next evaluate the `and`

, => False and True => False. Now recompose.

```
False or False => False
```

Try this on paper if needs be, but do not use the computer to solve them. Get in the practice and let your brain learn.
