A.you get a symmetric matrix.
you can add to a non symmetric matrix a diagonal symmetric matrix and get a symmetric one but not always and i don t know if you can get one by multiplying two non symmetric matrices.
Start by putting whole numbers together and fractions together;
5-2 + 2/7-5/7
3+(-3/7)
=3-3/7
=21/7-3/7
=18/7
=2
