If
A = [ 8 6 -3 ]
[5 -5 9 ]
And,
B = [ 7 -9 ]
[ -6 4 ]
highlight%28Then%29 A+B =

I am really not sure how to do this.

Hey,  they want you to add two matrices,  2x3-matrix  A  and  2x2-matrix  B,

A = %28matrix%282%2C3%2C+8%2C6%2C-3%2C+5%2C+-5%2C9%29%29 and B = %28matrix%282%2C2%2C+7%2C-9%2C+-6%2C4%29%29.

Then answer is:  it is not possible to add these two matrices,  because they have inappropriate dimensions.

They only want to check if you know rules.  That's all.
