Get introduced to the concept of metaprogramming. Learn how to level up your programming skills by discovering the full potential of the macro system in Elixir. Understand the ins and outs of metaprogramming at a fundamental level and write incredible libraries by doing more with less code.

Metaprogramming in Elixir

In the `MathTest` module that we created, what would be the output of the following `assert` expression:

`assert "true" == true`

In the <code>MathTest</code> module that we created, what would be the output of the following <code>assert</code> expression:
<code>assert &quot;true&quot; == true</code>

```
=============================================== 
FAILURE:  "Example Test"
=============================================== 
Expected: 49.0
to be equal to: 7
```

=============================================== 
Expected: 7
to be equal to: 14.0
```

Expected: 14.0
to be equal to: 7
```

In the `MathTest` module that we created, what would be the output of the following `assert` expression:

`assert 49 / 7 + 7 == 7`

In the <code>MathTest</code> module that we created, what would be the output of the following <code>assert</code> expression:
<code>assert 49 / 7 + 7 == 7</code>

Other than the `if` macro, which Elixir construct would be best suited for recreating the `unless` macro?

Other than the <code>if</code> macro, which Elixir construct would be best suited for recreating the <code>unless</code> macro?

to be equal to: 16

Expected:       455.0
to be equal to: 16

In the `MathTest` module that we just created, what would be the output of the following `assert` expression:

`assert 56 * 8 + 8 - 8 / 8 == 16`

In the <code>MathTest</code> module that we just created, what would be the output of the following <code>assert</code> expression:
<code>assert 56 * 8 + 8 - 8 / 8 == 16</code>

Can't be concluded from the given information.

Would the output of these two expressions yield the same result in our `MathTest` module?
```
assert (56 * 8) + (8 - (8 / 8)) == 8
```
and
```
assert 56 * 8 + 8 - 8 / 8 == 8
```


Would the output of these two expressions yield the same result in our <code>MathTest</code> module?
<pre><code>assert (56 * 8) + (8 - (8 / 8)) == 8
</code></pre>
and
<pre><code>assert 56 * 8 + 8 - 8 / 8 == 8
</code></pre>

Which of the following assertion expressions are correct? Select the two correct options.


Which of the following assertion expressions are correct? Select the two correct options.

The outside bound variables are quoted and then unquoted

The outside bound variables are unquoted only a single time.

The outside bound variables are quoted only a single time

What does the `bind_quoted` option ensure in a block? 

What does the <code>bind_quoted</code> option ensure in a block?
