+### Derive

+Add computed columns using [`pandas.DataFrame.eval`](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.eval.html#pandas.DataFrame.eval), no AI agents needed.
+
+```python
+from everyrow.ops import derive
+
+result = await derive(
+    input=orders_dataframe,
+    expressions={"total": "price * quantity"},
+)
+```
+
+`derive` is useful for adding simple calculated fields before or after other operations. It's much faster and cheaper than using AI agents to do the computation.
