# Introduction

Most programmers probably already know this, but for beginner programmers, it is quite frequently unknown or overlooked.

When you evaluate expressions you need not evaluate "If <expression> = true then", you simply evaluate "If <expression> then"

This is because <expression> already produces a Boolean value, and an if then branch breaks down to the following logic:

`1.`

`If`

`<Expression> then`

`2.`

` `

`'True was the case`

`3.`

`Else`

`4.`

` `

```
'False was the
case
```

`5.`

`End`

`If`

So when you evaluate the following expression for example:

(1+2 = 4)

This will automatically become false, because 1+2 does not equal 4.

True will always = true (It is what it is!)

False will always = false(It is what it is!)

Which means that saying:

`1.`

`If`

`(1+2=4) = true then`

`2.`

` `

`'True was the case`

`3.`

`Else`

`4.`

` `

```
'False was the
case
```

`5.`

`End`

`If`

is effectively saying the same as saying

`1.`

`If`

`<`

`Boolean`

`> = true then`

`2.`

```
2.
```

`'True was the case`

`3.`

`3.`

`Else`

`4.`

```
4.
```

`'False was the case`

`5.`

`5.`

`End`

`If`

But since a Boolean "is what is", we need not check if "<Boolean>" = true...

So the following is the same as above:

`1.`

`If`

`<`

`Boolean`

`> then`

`2.`

` `

`'True was the case`

`3.`

`Else`

`4.`

` `

```
'False was the
case
```

`5.`

`End`

`If`

And the following is just as absurd as evaluating true in an expression:

`1.`

`If`

`(((((1 + 2) = 3) = `

`True`

```
) =
```

`True`

```
) =
```

`True`

```
)
```

`Then`

`2.`

` `

`'True was the case`

`3.`

`Else`

`4.`

` `

```
'False was the
case
```

`5.`

`End`

`If`

In conclusion, try to remember, "It is what it is."
