Step 1
Given matrix:
A=[2003],B=[5004]
Step 2
Now, AB=(2003)(5004)
Multiply the rows of the first matrix by the columns of the second matrix :
=(2(5)+0020+040(5)+(3)000+(3)4)
=(100012)
Step 3
and
BA=(5004)(2003)
Multiply the rows of the first matrix by the columns of the second matrix : =((5)2+00(5)0+0(3)02+4000+4(3))
=(100012)
