You have 9 cards with the one of the numbers 1-9 written on each and they are shuffled, you pick a card and write down the number and this is the tens digit of a 2-digit number, then you put the card back. You pick another card and this number is the units digit. so you might have a number like 27 if you pik a 2 then a 7.
