 Perform and explain (Posted on 2017-12-12)
My magician gives you 3 regular dice and asks you to do the following, while he is out of the room:
"Roll them, and write in sequence the three results, followed by a 3-digit number representing the hidden sides of the rolled dice.

Once you got the 6â€“digit number, divide it by 111.

THEN CALL ME."

Then he exits and you roll 1,2,4 and write down 124653, divide by 111 and get 1123. The magician upon entering the room gets the result and quips within a second 1,2,4.

How did he do it?

Each row below shows the original augmented number; then the 4-digit number as presented to the magician. the last number shown on the line consists of three digits: the first is the first digit of what's presented to the magician; the second is the sum of the first two digits of that number; and the third is the sum of the first three digits of the presented number.  Lo and behold, they show the first three digits of the original augmented number, that is, the three dice rolls.
