Table calculations are one of the most powerful tools you have when it comes to building personalized reports in Lightspeed Analytics. 

Some of the benefits:

• They can help with custom sorting. This highlights areas in your Retail POS activity that you want to focus on.
• They can help prepare custom visualizations. This displays activity in Retail POS in a quick and meaningful way. 
• They can help do the math and logical problems for you.
• They can help prepare data for more in-depth analysis, exporting to spreadsheet software, or other analytic programs.

The language of calculations starts simply and can get quite sophisticated, depending on your comfort level. (More advanced Retail POS users may be interested in learning about Looker functions and operators.)
