The multiplication sign is visible in InputForm Sum[A[i][j]*B[i][j], {i, 1, 2}, {j, 1, 2}] // InputForm A[1][1]*B[1][1] + A[1][2]*B[1][2] + A[2][1]*B[2][1] + A[2][2]*B[2][2] Bob Hanlon ---- Volkan <visbuga at gmail.com> wrote: ============= 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
