## Introduction

```4 + 10 ```
```ans = 14 ```
```5 *10 + 6 ```
```ans = 56 ```
```(6 + 6) / 3 ```
```ans = 4 ```

## The ans Variable

```4 + 5 ```
```ans = 9 ```
```ans ```
```ans = 9 ```
```ans + 10 ```
```ans = 19 ```

```a = 10 ```
```a = 10 ```
```b = 20 ```
```b = 20 ```
```c = 30 ```
```c = 30 ```
```a ```
```a = 10 ```
```the_average = (a + b + c) / 3 ```
```the_average = 20 ```

## Listing Currently Defined Variables and Clearing Variables

```clear % clear variables from memory ```
```a = 5 ```
```a = 5 ```
```b = 6 ```
```b = 6 ```
```whos ```
``` Name Size Bytes Class Attributes a 1x1 8 double b 1x1 8 double ```
```clear whos ```

## Suppressing results with semicolons

```a = 10; b = 20; c = 30; d = 40; ```
```the_average = (a + b + c + d) / 4 ```
```the_average = 25 ```
```the_average; ```
```b ```
```b = 20 ```
```e = 50 ```
```e = 50 ```
```the_blank_average = (a + b + c + d + e) / 5; the_blank_average ```
```the_blank_average = 30 ```

## Variable Names and Assigning Strings to Variables

```some_text = 'This is some text assigned to a variable!'; some_text ```
```some_text = This is some text assigned to a variable! ```
```a = 5; b = '5'; a/b ```
```ans = 0.0943 ```
```a*b ```
```ans = 265 ```
