compute the indicated matrices (if possible). B - C Let A=[30−15],B=[4−21023],C=[123456],D=[0−3−21],E=[42],F=[−12]

Given B=[4−21023],C=[123456] procedure Let A and B be any matrices , if A-B exits then order of A and B must be same. Let A be a matrix,order of A is number of rows × number of columns Solution B=[4−21023] and C=[123456] here, order of B is 2×3 order of C is 3×2 now, order of B is not equal to order of C Hence B-C does not exit.

compute the indicated matrices (if possible). B - C
Let

A = [\begin{matrix} 3 & 0 \\ - 1 & 5 \end{matrix}], B = [\begin{matrix} 4 & - 2 & 1 \\ 0 & 2 & 3 \end{matrix}], C = [\begin{matrix} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{matrix}], D = [\begin{matrix} 0 & - 3 \\ - 2 & 1 \end{matrix}], E = [\begin{matrix} 4 & 2 \end{matrix}], F = [\begin{matrix} - 1 \\ 2 \end{matrix}]

Given

B = [\begin{matrix} 4 & - 2 & 1 \\ 0 & 2 & 3 \end{matrix}], C = [\begin{matrix} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{matrix}]

procedure
Let A and B be any matrices , if A-B exits then order of A and B must be same.
Let A be a matrix,order of A is number of rows

\times

number of columns
Solution

B = [\begin{matrix} 4 & - 2 & 1 \\ 0 & 2 & 3 \end{matrix}] and C = [\begin{matrix} 1 & 2 \\ 3 & 4 \\ 5 & 6 \end{matrix}]

here,
order of B is

2 \times 3

order of C is

3 \times 2

now, order of B is not equal to order of C
Hence B-C does not exit.
