Is XII even or odd?

### A good answer might be:

Even. The representation does not change the properties the number (although it often makes it easier to determine those properties).

# Positional Notation

The decimal system is a positional notation for representing numbers. This means that the representation consists of a string of digits. The position of each digit in the string is significant. Think of each position as a numbered slot where a digit can go.

    ____4 ____3 ____2 ____1 ____0

Positional notation has many advantages. It is compact: "78" is shorter than "LXXIIX". Computation is easy. `LXXIIX` times `XLIIV` is hard to do using only the Roman system.
