    Linear algebra problem (standard matrix for a linear operator)

    I tried to multiply the matrix 1 0 0 0 1 0 0 0 1 by the vectors given but I got this [x-y y+2x 2x+y+z] Doesn't make sense

    Linear algebra problem (standard matrix for a linear operator)

    So the answer would be [x-y 0 0 0 y+2z 0 0 0 2x+y+z] ? or is the answer [x-y y+2x 2x+y+z] I understand how to multiply matrices, but now this looks backward to me. Yes I am taking a distance learning class and there is no professor, just me reading a textbook which has terminology that rarely...
