Practice Questions on Subtraction of Matrices
Q1. Subtract the matrices: P = [Tex]\begin{bmatrix} 5 & 9\\2 & 4 \end{bmatrix}[/Tex] and Q = [Tex]\begin{bmatrix} 0 & -3\\ 7 & 14 \end{bmatrix}[/Tex]
Q2. Subtract the matrices A = [Tex]\begin{bmatrix} -8& 3& 9\\ -1 & 2&6\\ 5& -12&4 \end{bmatrix}[/Tex] and B = [Tex]\begin{bmatrix} -3& 5& 13\\ -10 & 23&0\\ 7& -1&22 \end{bmatrix}[/Tex]
Q3. Compute R – S where R = [Tex]\begin{bmatrix} -8& 3& 9&10\\ -1 & 2&6&2\\ 5& -12&4&7 \end{bmatrix}[/Tex] and S = [Tex]\begin{bmatrix} 1& 6& 3&0\\ -1 & -2&-8&2\\ 0& 5&4&-7 \end{bmatrix}[/Tex]
Q4. Subtract the matrices C = [Tex]\begin{bmatrix} -18& 30 \\ -10 & 21\\ \end{bmatrix}[/Tex] and D = [Tex]\begin{bmatrix} -1& 3& 12\\ -2 & 4&6\\ 5& -3&14 \end{bmatrix}[/Tex]
Subtraction of Matrices
Subtraction of matrices is addition of the negative of a matrix to another matrix which means A – B = A + (-B). The subtraction of the matrix is subtracting the corresponding row-column element of one matrix with same row-column element of another matrix.
