If the 2 × 2 matrix A whose rows are (2, 3) and (4, 5) is multiplied by itself, then the product, usually written A2, has rows (16, 21) and (28, 37).

WebBecause matrix A has 3 rows, and matrix B has 2 columns, matrix C will be a 3x2 matrix. 3 rows, 2 columns. Now, the rules for matrix multiplication say that entry i,j of matrix C is the dot product of row i in matrix A and column j in matrix B. We can use this information to find every entry of matrix C. Here are the steps for each entry:
