Answer

[4.4 ... 4.5] [9.5 .... -10.2] [3.4 ... -2.6]

Work Step by Step

You 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] Add each corresponding element because the two matrices have the same size: [0.4+4 ... 1.5+3] [3.2+6.3 .... -3+(-7.2)] [1.5+1.9 ... -2.1+(-0.5)] The new matrix is: [4.4 ... 4.5] [9.5 .... -10.2] [3.4 ... -2.6]
