About

This is a simple JavaScript formula calculator that can evaluate mathematical expressions given as strings. It supports basic arithmetic operations such as addition, subtraction, multiplication, and division, as well as parentheses for grouping. The calculator follows the standard order of operations (PEMDAS/BODMAS) to ensure accurate results.

The core function, `calculate(formula)`, takes a string input representing the mathematical expression and returns the computed result. It handles various edge cases, including negative numbers and nested parentheses.

This tool can be useful for quick calculations directly in the browser without needing to rely on external calculators or software.
