Question

How do you simplify `[(12,0,8),(9,15,-11)]-[(-3,0,4),(9,2,-6)]`?

Answer 1

Here is a reference for Adding and Subtracting Matrices

Explanation:

Given:

#[ (12,0,8), (9,15,-11) ] − [ (−3,0,4), (9,2,−6) ] =#

#[ (12 - -3,0 - 0,8-4), (9 - 9, 15-2,-11- -6) ] = #

#[ (15,0,4), (0, 13,-5) ] #
