Explanation:
Here is an example
Find the first row of the product
Take the first row of
Now multiply times the first column and add to get the first number in the first row of the answer:
Next multiply times the second column and add to get the second number in the first row of the answer:
(If there were more columns in the second matrix, we would continue this process.)
A this point we know that the product looks like:
Find the second row of the product
Find the second row of the product by the same process using the second row of
Make the second row veritcal, muliptly and add.
A this point we know that the product looks like:
Find the third row of the product.
