Which is the correct way to multiply 8 × 6?

You can add the digits in any order you like, but I find it helpful to always start with the bottom-left and top-right product (here the 8 × 6) and systematically move simultaneously rightwards on the bottom number and leftwards on the top number. By now the pattern should be fairly clear, so I’ll continue with minimal commentary:
