Guide to Multiplying Matrices

This solver will guide you through multiplying two matrices. Given two matrices A and B, the solver will compute AB (ie the product of the matrices A and B).

Enter the numerical entries (numbers only) for each matrix. Separate each entry with a comma. When a new row is needed, use a semicolon. For example, to enter the matrix %28matrix%283%2C3%2C1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9%29%29

%28matrix%283%2C3%2C1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9%29%29

, enter the following: 1,2,3;4,5,6;7,8,9

Entries for matrix A

Entries for matrix B

Note: Remember that the number of columns of matrix A must equal the number of rows of matrix B. Also, remember that matrix multiplication is NOT commutative. In other words, AB%3C%3EBA

in general. So make sure you enter the values in the correct order.

Please keep in mind that this solver doesn't do much error checking. So make sure that you read the instructions and enter the values in carefully. Also, be sure to verify the answer.
