Question

given the matrices a and b shown below, find a + b.
a = \

$$\begin{bmatrix} 0 & -5 \\\\ 2 & 4 \\\\ 0 & 4 \\\\ -5 & -2 \\end{bmatrix}$$

\quad b = \

$$\begin{bmatrix} -2 & -3 \\\\ 1 & 1 \\\\ 2 & -5 \\\\ -2 & 0 \\end{bmatrix}$$

answer attempt 1 out of 2
rows: 2 \boldsymbol{\circleddash} \boldsymbol{\oplus} \quad columns: 2 \boldsymbol{\circleddash} \boldsymbol{\oplus}
\

$$\begin{bmatrix} & \\\\ & \\end{bmatrix}$$

Explanation:

Step1: Add corresponding elements

Add each element of A to the same-position element of B:
First row: $0+(-2)=-2$, $-5+(-3)=-8$
Second row: $2+1=3$, $4+1=5$
Third row: $0+2=2$, $4+(-5)=-1$
Fourth row: $-5+(-2)=-7$, $-2+0=-2$

Answer:

$$\begin{bmatrix}-2 & -8 \\3 & 5 \\2 & -1 \\-7 & -2\end{bmatrix}$$
