import geemap.core as geemap
```

### Colab (Python)

```python
display(ee.Array([10]).subtract(1))  # [9]

display(ee.Array([-1, 0, 1]).subtract(2))  # [-3, -2, -1]
display(ee.Array([-1, 0, 1]).subtract([-5, 6, 7]))  # [4, -6, -6]

empty = ee.Array([], ee.PixelType.int8())
display(empty.subtract(empty))  # []
