Before we dive into matrix addition and subtraction, let’s understand what matrices are. Matrices are rectangular arrays of numbers, symbols, or expressions arranged in rows and columns. A 2×2 matrix, as the name suggests, contains 2 rows and 2 columns, making it a fundamental building block in linear algebra.

2x2 Matrix Addition and Subtraction Formula

The Structure of a 2×2 Matrix

A 2×2 matrix looks like this:

| a b | | c d |

Here, ‘a,’ ‘b,’ ‘c,’ and ‘d’ represent the individual elements of the matrix.

Matrix Addition

Adding Two Matrices

Matrix addition is a straightforward process that involves adding corresponding elements of two matrices. To add two 2×2 matrices, follow these steps:

  1. Add the elements in the first row of the first matrix to the elements in the first row of the second matrix.
  2. Add the elements in the second row of the first matrix to the elements in the second row of the second matrix.

Let’s illustrate this with an example:

Example:

Matrix A: | 1 2 | | 3 4 |

Matrix B: | 5 6 | | 7 8 |

Resultant Matrix C: | 6 8 | | 10 12 |

Properties of Matrix Addition

Matrix addition has some important properties:

Commutative Property

Matrix addition is commutative, which means that changing the order of addition doesn’t affect the result. In other words, A + B = B + A.

Associative Property

Matrix addition is also associative, meaning that (A + B) + C = A + (B + C).

Matrix Subtraction

Subtracting Two Matrices

Matrix subtraction is similar to addition but involves subtracting the corresponding elements of two matrices. To subtract two 2×2 matrices, follow these steps:

  1. Subtract the elements in the first row of the second matrix from the elements in the first row of the first matrix.
  2. Subtract the elements in the second row of the second matrix from the elements in the second row of the first matrix.

Let’s use the same matrices A and B from our previous example to illustrate subtraction:

Example:

Matrix A: | 1 2 | | 3 4 |

Matrix B: | 5 6 | | 7 8 |

Resultant Matrix D: | -4 -4 | | -4 -4 |
