## How to Add Two Matrices?

**Matrix **is a mathematical function to represent a set of data usually a matrix used is a 2D matrix and used for purposes of vector addition, vector multiplication etc. To add the given matrices:

** Addition **= \( \begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \end{bmatrix} \) + \( \begin{bmatrix} j & k & l \\ m & n & o \\ p & q & r \end{bmatrix} \) \( = \begin{bmatrix} a+j & b+k & c+l \\ d+m & e+n & f+o \\ g+p & h+q & i+r \end{bmatrix} \)

**Solved Examples on Matrix Addition Calculator**

**Example 1:**

Find the sum of given matrices \( \begin{bmatrix} 1 &2 \\ 3 & 4 \end{bmatrix} \) & \( \begin{bmatrix} 2 &1 \\ 4 & 2 \end{bmatrix} \)

**Solution:**

Given: Matrix 1 =** ** \( \begin{bmatrix} 1 &2 \\ 3 & 4 \end{bmatrix} \) & Matrix 2 = \( \begin{bmatrix} 2 &1 \\ 4 & 2 \end{bmatrix} \)

Matrix 1 + Matrix 2 = \( \begin{bmatrix} 1 &2 \\ 3 & 4 \end{bmatrix} \) + \( \begin{bmatrix} 2 &1 \\ 4 & 2 \end{bmatrix} \)

= \( \begin{bmatrix} 1+2 &2+1 \\ 3+4 & 4+2 \end{bmatrix} \)

= \( \begin{bmatrix} 3 &3 \\ 7 & 6 \end{bmatrix} \)

**Example 2:**

Find the sum of given matrices \( \begin{bmatrix} 3 &-4 \\ 7 & -8 \end{bmatrix} \) & \( \begin{bmatrix} 4 &2 \\ 7 & -4 \end{bmatrix} \)

**Solution:**

Given: Matrix 1 =** ** \( \begin{bmatrix} 3 &-4 \\ 7 & -8 \end{bmatrix} \) & Matrix 2 = \( \begin{bmatrix} 4 &2 \\ 7 & -4 \end{bmatrix} \)

Matrix 1 + Matrix 2 = \( \begin{bmatrix} 3 &-4 \\ 7 & -8 \end{bmatrix} \) + \( \begin{bmatrix} 4 &2 \\ 7 & -4 \end{bmatrix} \)

= \( \begin{bmatrix} 3+4 &-4+2 \\ 7+7 & -8-4 \end{bmatrix} \)

= \( \begin{bmatrix} 7 &-2 \\ 14 &-12 \end{bmatrix} \)

Similarly, you can use the calculator to add the given matrices

- \( \begin{matrix} 2 & -1 & 3 \\ 4 & -5 & 1 \\ 1 & 6 & 7 \end{matrix} \) + \( \begin{matrix} 3 & -4 & 7 \\ 8 & 1 & 5 \\ 6& -5 & 3 \end{matrix} \)
- \( \begin{matrix} -4 &2 \\ -3 & 4 \end{matrix} \) + \( \begin{matrix} 2 &1 \\ 4 & 2 \end{matrix} \)
