🧮 Step-by-Step Matrix Calculator

A beginner-friendly desktop app that solves 2×2 and 3×3 matrix operations step-by-step — made for students, math enthusiasts, and educators. Built using PyQt6 with a clean and modern GUI, this tool doesn’t just give the answer — it shows every step involved in calculating matrix addition, subtraction, multiplication, determinant, and inverse.
