Math Problem Statement
Evaluate the given expression. Take A =
0 −2
−2 0 1 1 and B =
−0.25 3
0 −0.25 −2 −1 . A + B
Solution
We are given two matrices and :
0 & -2 \\ -2 & 0 \\ 1 & 1 \end{pmatrix}, \quad B = \begin{pmatrix} -0.25 & 3 \\ 0 & -0.25 \\ -2 & -1 \end{pmatrix}.$$ To compute $$A + B$$, we add the corresponding elements of the two matrices. $$A + B = \begin{pmatrix} 0 + (-0.25) & -2 + 3 \\ -2 + 0 & 0 + (-0.25) \\ 1 + (-2) & 1 + (-1) \end{pmatrix}$$ This simplifies to: $$A + B = \begin{pmatrix} -0.25 & 1 \\ -2 & -0.25 \\ -1 & 0 \end{pmatrix}$$ Thus, the sum $$A + B$$ is: $$A + B = \begin{pmatrix} -0.25 & 1 \\ -2 & -0.25 \\ -1 & 0 \end{pmatrix}.$$ Would you like further details or have any questions?
