i solved it using that method

i want to transform a matrix from a standart basis to basis B

A-out old matrix

X- the old basis

Y-the new basis

S-the transformation matrix

S^-1 -its inverse

N-resolt

i did

Y|X>>>I|S

S|I=I|S^-1

N=S*A*S^-1

the problem is with the solution that i was given

but the problem is that the solution that i was given is totaly different

A-old matrix

B-new basis

N-answer

i noticed that he takes

B|A>>> I|N

thats totaly different i cant see any logic in that

and he got a different answer from me

and he got full points for that

that gives me a great dought in my method

can you please tell were am i wrong??
