# C# Math

The C＃数学 class has many methods that allows you to perform mathematical tasks on numbers.

## Math.Max(x,y)

The `Math.Max(x,y)` method can be used to find the highest value of x and y:

### Example

``````Math.Max(5, 10);
``````

## Math.Min(x,y)

The `Math.Min(x,y)` method can be used to find the lowest value of of x and y:

### Example

``````Math.Min(5, 10);
``````

## Math.Sqrt(x)

The `Math.Sqrt(x)` method returns the square root of x:

### Example

``````Math.Sqrt(64);
``````

## Math.Abs(x)

The `Math.Abs(x)` method returns the absolute (positive) value of x:

### Example

``````Math.Abs(-4.7);
``````

## Math.Round()

`Math.Round()` rounds a number to the nearest whole number:

### Example

``````Math.Round(9.99);
``````

## Exercise:

Use the correct method to print the highest value of `x` and `y`.

```int x = 5;
int y = 10;
Console.WriteLine(Math.(x, ));
```
