#((4),(1),(-3))+((6),(-5),(8))=((10),(-4),(5))#

Explanation:

When you have two matrices of the same order i.e. same rows and columns, you can just add respective elements to form a new matrix of the same order.

For example, #((a_1),(a_2),(a_3))+((b_1),(b_2),(b_3))=((a_1+b_1),(a_2+b_2),(a_3+b_3))#

Hence #((4),(1),(-3))+((6),(-5),(8))=((4+6),(1+(-5)),((-3)+8))=((10),(-4),(5))#
