Math Calculator
Professional mathematical conversions and calculations. Convert fractions, decimals, number systems, and perform geometric calculations with step-by-step solutions.
Performs matrix operations: addition, subtraction, multiplication, transposition, and finding the determinant or inverse.
Matrix multiplication is NOT commutative: AB ≠ BA in general. This asymmetry is fundamental to quantum mechanics, where the order of measurements matters — measuring spin along X then Y gives different results than Y then X.
Multiplying matrices of incompatible dimensions — A×B requires A to be m×n and B to be n×p (the inner dimensions must match).
