Matrix is a way of arrangement of numbers, sometimes expressions and symbols, in rows and columns. Matrix formulas are used to solve linear equations and calculus, optics, quantum mechanics, and other mathematical functions. If the two matrices are of the same size as their rows and columns, then they can be added, subtracted, and multiplied element by element. Let us learn the matrix formulas along with a few solved examples.
