What is in the deck

Every sum in the range, both ways round: each side of the plus sign runs the whole range, so 0 to 10 gives 121 cards. 3 + 8 and 8 + 3 are both in the pack for the same reason both orders are in the times tables: they are the same total and they are not the same card.

Eight to a sheet is 16 sheets and 32 pages counting the backs. The card is 95 by 69.3 mm and both sides set at 64 pt.

Setting the range

From and to take anything from 0 to 20. Bonds to ten are 0 to 10, which is what the bench above is set to. Bonds to twenty are 0 to 20, which is more cards than this press will set in one go, so narrow the bottom of the range as well: 10 to 20 is 121 cards again.

The press stops at 240 cards. Past that a deck is not a deck, it is a filing job.

Zero is in the range

0 + 0 and 0 + 7 are cards, because zero is a number in the range like any other. Start the range at 1 if you would rather not have them.
