Answer
[4.4 ..... 4.5]
[9.5 .......-10.2]
[3.4 .... -2.6]
Work Step by Step
We have two matrices:
[0.4 ..... 1.5]
[3.2 .......-3]
[1.5 .... -2.1]
AND...
[4 .... 3]
[6.3.... -7.2]
[1.9 .... -0.5]
The two matrices have the same size, so we add each corresponding element:
[0.4+4 ..... 1.5+3]
[3.2+6.3 .......-3+(-7.2)]
[1.5+1.9 .... -2.1+(0.5)]
New matrix:
[4.4 ..... 4.5]
[9.5 .......-10.2]
[3.4 .... -2.6]
