The number of columns in the first one must the number of rows in the second one. If the result was 27 the 2 would be carried to the next diagonal. Add up the rows you got in step 3 to get your answer.

The First Row “Hits” The First Column, Giving Us The First Entry Of The Product.


If matrix a [m, n] and matrix b [n, z] are. Let’s say we want to multiply matrix a with matrix b to compute matrix c. Any tens digits are carried over to be added in the next diagonal, e.g.

[1] These Matrices Can Be Multiplied Because The First Matrix, Matrix A, Has 3 Columns, While The Second Matrix, Matrix B, Has 3 Rows.


The number of columns in the first one must the number of rows in the second one. When the grid has been completed all the numbers along the same diagonals are added together. The multiplication will be like the below image:

1*1=1 1*3=3 1*5=5 1*7=7 2*2=4 2*4=8 2*6=12 2*8=16.

A) multiplying a 2 × 3 matrix by a 3 × 4 matrix is possible and it gives a 2 × 4 matrix as the answer. On the act math test, you’ll probably have to multiply pairs of matrices that have either one row or one column. Ans.1 you can only multiply two matrices if their dimensions are compatible, which indicates the number of columns in the first matrix is identical to the number of rows in the second matrix.
