Matrix Add/Subtract

Use this calculator to perform addition or subtraction on two matrices. Enter your matrices, select the operation, and get the result instantly.

Enter elements separated by commas or spaces. Use a new line for each row. E.g., 1 2 3 4

Enter elements separated by commas or spaces. Use a new line for each row. E.g., 5 6 7 8

Choose to add or subtract Matrix B from Matrix A.

How it works

Use this calculator to perform addition or subtraction on two matrices. Enter your matrices, select the operation, and get the result instantly.


The Formula
For two matrices A and B of the same dimensions (m x n):

Matrix Addition: C = A + B, where C_ij = A_ij + B_ij

Matrix Subtraction: D = A - B, where D_ij = A_ij - B_ij

Worked Example
  1. Example: Adding Two 2x2 Matrices

    Let Matrix A = [[1, 2], [3, 4]] and Matrix B = [[5, 6], [7, 8]]. To add them, we add corresponding elements: C_11 = A_11 + B_11 = 1 + 5 = 6 C_12 = A_12 + B_12 = 2 + 6 = 8 C_21 = A_21 + B_21 = 3 + 7 = 10 C_22 = A_22 + B_22 = 4 + 8 = 12 Result Matrix C = [[6, 8], [10, 12]]


Tips, Assumptions & Limitations
  • Matrices must have the exact same number of rows and columns to be added or subtracted.
  • Enter matrix elements separated by commas or spaces. Use a new line for each new row.
  • Ensure all elements are valid numbers. Non-numeric inputs will cause an error.
FAQ

Matrices are rectangular arrays of numbers, symbols, or expressions arranged in rows and columns. They are fundamental in linear algebra and used in various fields like physics, engineering, computer graphics, and economics.

You can only add or subtract two matrices if they have the exact same dimensions (i.e., the same number of rows and the same number of columns). If their dimensions differ, the operation is undefined.

To add or subtract matrices, you simply add or subtract the corresponding elements in each position. For example, to find the element in the first row, first column of the result matrix, you add/subtract the elements in the first row, first column of the original matrices.

Yes, the calculator can handle matrices of various sizes, limited by practical input constraints. Ensure your input format is correct for larger matrices (each row on a new line, elements separated by commas or spaces).
