Question 864645: [15 -30 30]+ [-3 -6 9]-[62 45 36]=? These Matrices should be standing vertical 1x1

This is how far I got but I actually don't know what I'm doing. I just added the first two Matrices then got an answer and subtracted it by the remaining matices. Can you please provide me with steps to follow I would greatly appreciate it.
[12 -36 39]-[62 45 36]= [-50 -9 3]
