To add two matrices, we need to add the corresponding terms of the two matrices. Therefore, [ B ] + [ C ] =

11eac9cf_f873_244e_a07b_056b10423f03_TB7816_00
11eac9cf_f873_244d_a07b_abafbdee2d05_TB7816_00
And then we need to multiply the resulting matrix by the scalar A. Therefore, the final matrix is:
