# operator +(Vector3, Vector3)

> Adds two three-dimensional vectors with component-wise addition.

## Definition

* **Type:** Operator
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static Vector3 operator +(Vector3 a, Vector3 b)
```

### Parameters

**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): The left operand of the addition.**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): The right operand of the addition.

### Returns

| Type                                                              | Description                                                                       |
| ----------------------------------------------------------------- | --------------------------------------------------------------------------------- |
| [Vector3](/engine/6000.5/script-reference/unityengine/vector3.md) | A Vector3 initialized with the component-wise sum of the left and right operands. |

### Remarks

Adds corresponding x,y,z components of the left and right Vector3 operands and returns a Vector3 initialized with those component sums as the result.

### Examples

```csharp
// prints (5.0,7.0,9.0)

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        print(new Vector3(1, 2, 3) + new Vector3(4, 5, 6));
    }
}
