Addition/ subtraction of matrices
Last updated at April 16, 2024 by Teachoo
We can add or subtract matrices only if they are of the same order
Let’s actually add them.
When adding two matrices, each corresponding element gets added
Similarly,
Example [■8(3&2@1&4)][■8(3&2@1&4@5&3)] We cannot add them But we can add [■8(3&2@1&4)][■8(−9&2@−1&3)] We can add them [■8(3&2@1&4@5&3)][■8(−2&5@−8&12@0&−18)] We can add them [■8(3&2@1&4)]+ [■8(−9&2@−1&3)] =[■8(3+(−9)&2+2@1+(−1)&4+3)] =[■8(−6&4@0&7)] [■8(3&2@1&4@5&3)]−[■8(−2&5@−8&12@0&−18)] =[■8(3−(−2)&2−5@1−(−8)&4−12@5−0&3−(−18))] =[■8(3+2&−3@1+8&−8@5&3 +18)] =[■8(5&−3@9&−8@5&21)]
