I appreciate your work, thanks so much keep up the good work ✅
Hello Little P! Thanks very much for the positive feedback!
I didn’t get the same answer for the second question, ive also asked my friends and we all got the same answer it just didnt line up with yours. Apart from that, great website and thanks for the exercises.
Very nice and good explanation of matrix
Give some more examples of matrix
I want to more study about matrix that’s why I’m using Google
