# Numbers

## Numbers

The computer can also do regular math that you see in school. Use `Console.WriteLine`

to print out the result from the math expressions. No quotation marks are needed for numbers!

```
Console.WriteLine(5 + 4);
Console.WriteLine(6 * (9 - 7) / 3);
```

Here is the full list of math symbols that you can use:

Operator | Description | Operator | Description |
---|---|---|---|

`+` | Add | `\` | Divide |

`-` | Subtract | `%` | Modulo (remainder) |

`*` | Multiply | `(` ,`)` | Parenthesis |

## Fun Fact: Computer Division

The computer does division differently from your regular calculator. Computer division will exclude remainders or decimals. For example, `15 / 4`

produces `3`

, and not `3.75`

.

## Working Together

Try printing out the answers to the following to the console. Ensure your brackets are matched. Use a calculator (or mental math) to verify the computer produced the correct answer.

`2 - 19`

`(3 + 5) * 6`

`(13 + 5 * 8) / (6 - (3 + 7))`

## Fun Fact: Random Numbers

Here is how to print a random number between `1`

(inclusive) and `10`

(exclusive):

```
Random random = new Random();
Console.WriteLine(random.Next(1, 10));
```

Try to find where we use `Random`

in the GuessTheWord game! However, the details as to how this works is complicated, so we will skip this discussion.
