I know a guy who can multiply two large numbers as 3746 x 9852 etc. immediately. He said he can see different shapes or waves and colours in each number, then each number merged into another different shape and colour. He can then tell the number. This is not a magic, it's just because he can conceptualise very big numbers as we ordinary people do in relatively small numbers as 1 to 9.
