# Calculations

### **Bulk edit using calculations**

You can also edit multiple values at one using a calculation. Simply click on the calculator icon above a column and select “Bulk Edit”. A number of calculation options can be performed on the data. Select the operator and enter a value. When you hit “Update” the calculation will be performed and the values can be previewed. When you’re happy with the result, hit “Save”. The datasource data will be updated to reflect your calculations.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.infotopics.com/writebackextreme/features/tableau-extension/end-user/data-correction/calculations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
