Let A=1-12210,B=01-1123,andC=-123001
Find each of the following :
(vii) A-B-C
Calculation of the matrix A-B-C.
The subtraction of matrices is defined as the subtraction of corresponding elements of two or more matrices.
A-B-C=1-12210-01-1123--123001=1-12210-0--11-2-1-31-02-03-1=1-12210-0+1-1-4122=1-12210-1-1-4122=1-1-1--12--42-11-20-2=0-1+12+41-1-2=0061-1-2
Final answer: The result is 0061-1-2.
(iv) B+C
(v) A+B+C
