## 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

```

## Defining Your Own Variables

```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

```
