No.Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.
(4+5) - (2 x 3) = 3

3/2 − 6/5 = 3/10
14 - 1/3 = 13 and 2/3

4/6 - 3/6 = 1/6

3+2+3²-1 = 5+8-1=12
(4+5) - (2 x 3) = 3
A positiveIMPROVED: -2-6 = -8but if you have 2 - -3 then the minus's will become a PLUS, so it'll be 2+3 which is 5.
