## What are the disadvantages of the Pascaline mechanical calculator?

The disadvantage to the Pascaline was that it was limited to addition and positive numbers. In 1694, Leibniz improved the Pascaline by creating a machine that could also multiply. In 1820, Colmar improved the machine, the Arithometer, so it could do the four basic arithmetic functions.

## How high can you count on an abacus?

The wireframe may be used either with positional notation like other abacuses (thus the 10-wire version may represent numbers up to 9,999,999,999), or each bead may represent one unit (e.g. 74 can be represented by shifting all beads on 7 wires and 4 beads on the 8th wire, so numbers up to 100 may be represented).

**Which one is the oldest calculated device?**
