To extend a simple calculator to evaluate full arithmetic expressions—including those with mixed operators and parentheses—we structure the grammar in hierarchical layers, each representing a different precedence level. This ensures correct evaluation order without requiring explicit parentheses in every case.
The grammar is divided into three ...
