# Table math Maybe you do not like our sign conventions. Or want to run a calculation that involves several different columns in different ways. Or just change the formatting of a column of numbers. The data in DashArgos is editable just like a spreadsheet: you can write whatever formulas you want with the data you've extracted. [This look](https://dashargos.chainargos.com/looks/799) use the "table calculation" feature to: * Add two columns together: Net Amount * Change the format of a column: Negative Minting Formatted as $ * Do some algebra: Fraction Minting Each of these is set up as a custom field and you can see how it was set up by editing that field. You can even hide field you do not want -- for example, if you want to change the formatting you probably do not want to see our default formatting -- by going to Visualization->Series->Customizations and disabling "Cell Visualization." The data is still there but this hides it. --- # Agent Instructions: 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: ``` GET https://docs.chainargos.com/documentation/research/empirical-research/basics/table_math.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
