Returns x + y element-wise.

Example usages below.

Add a scalar and a list:

````x = [1, 2, 3, 4, 5]`
`y = 1`
`tf.add(x, y)`
`<tf.Tensor: shape=(5,), dtype=int32, numpy=array([2, 3, 4, 5, 6],`
`dtype=int32)>`
```

Note that binary `+` operator can be used instead:

````x = tf.convert_to_tensor([1, 2, 3, 4, 5])`
`y = tf.convert_to_tensor(1)`
`x + y`
`<tf.Tensor: shape=(5,), dtype=int32, numpy=array([2, 3, 4, 5, 6],`
`dtype=int32)>`
```

Add a tensor and a list of same shape:

````x = [1, 2, 3, 4, 5]`
`y = tf.constant([1, 2, 3, 4, 5])`
`tf.add(x, y)`
`<tf.Tensor: shape=(5,), dtype=int32,`
`numpy=array([ 2,  4,  6,  8, 10], dtype=int32)>`
```

For example,

````x = tf.constant([1, 2], dtype=tf.int8)`
`y = [2**7 + 1, 2**7 + 2]`
`tf.add(x, y)`
`<tf.Tensor: shape=(2,), dtype=int8, numpy=array([-126, -124], dtype=int8)>`
```

When adding two input values of different shapes, `Add` follows NumPy broadcasting rules. The two input array shapes are compared element-wise. Starting with the trailing dimensions, the two dimensions either have to be equal or one of them needs to be `1`.

For example,

````x = np.ones(6).reshape(1, 2, 1, 3)`
`y = np.ones(6).reshape(2, 1, 3, 1)`
`tf.add(x, y).shape.as_list()`
`[2, 2, 3, 3]`
```

Another example with two arrays of different dimension.

````x = np.ones([1, 2, 1, 4])`
`y = np.ones([3, 4])`
`tf.add(x, y).shape.as_list()`
`[1, 2, 3, 4]`
```

The reduction version of this elementwise operation is `tf.math.reduce_sum`

`x` A `tf.Tensor`. Must be one of the following types: bfloat16, half, float16, float32, float64, uint8, uint16, uint32, uint64, int8, int16, int32, int64, complex64, complex128, string.
`y` A `tf.Tensor`. Must have the same type as x.
`name` A name for the operation (optional)
