AbstractTotals

What it does

This abstract class provides functionality for calculating totals (sum, average, or custom expressions) for grid columns in Magento 2's admin backend.

Developers extend this class when they need to display summary rows with calculated values at the bottom of admin grids, such as order totals, product quantities, or revenue summaries.

It supports mathematical expressions like addition, subtraction, multiplication, and division across multiple columns.
