    How MCMLXXIX is built

    Roman numerals are written one decimal place at a time, largest first.

    1. Mthousands · 1M is 1,000.
    2. CMhundreds · 9C before M means 1,000 − 100 = 900. This saves writing DCCCC.
    3. LXXtens · 7L (50) plus XX (20) makes 70.
    4. IXones · 9I before X means 10 − 1 = 9. This saves writing VIIII.

    1,000 + 900 + 70 + 9 = 1,979

    The pairs CM and IX use subtraction: a smaller letter before a larger one is taken away from it. Only six pairs work this way: IV, IX, XL, XC, CD and CM. More on subtraction
