how to keep multiplication sign "*" ( Please)

How can I keep the multiplication sign in a symbolic calculation
output such as:

Sum[A[i][j] *B[i][j], {i, 1, 2}, {j, 1, 2}]


gives
A[1][1] B[1][1] + A[1][2] B[1][2] + A[2][1] B[2][1] + A[2][2] B[2][2]

but what I want is it should seem like

A[1][1] *B[1][1] + A[1][2] *B[1][2] + A[2][1] *B[2][1] + A[2][2] *B[2]
[2]

Is this possible? Please help about this...

thanks
