Are you seriously trying to suggest that machine is better than a computer, Jrabbit? No I'm not suggesting that at all.
All it could do was add.

Reading is a skill.

The typical use of this machine was to total up money. That's why keys in the right-hand column are black. The ones, tens and hundreds columns are white. The thousands, 10Ks and 100Ks are black. Simple visual interface.

So at the end of a business day, the cash register is emptied and counted out. Each denomination of bills would be entered separately (X dollars in singles, $Y in fives, etc). No one wanted to punch in all those zeroes, and the machine didn't need them in order to add "nothing" to a given column.

Got it now?
