When multiplying matrices, you first need to look at the dimensions of both matrices. The term dimension refers to the size of the matrix. The first number represents the number of rows in the matrix and the second number refers to the number of columns.

And now two general matrices, A and B, say. The matrix product AB is formed by multiplying every row of A with every column of B, in the way described in Step 1 above. The resulting numbers are arranged in a new matrix: the mth row in A times the nth column in B gives the number at position (m,n) in AB:
