How VI Is Built

VI is the first Roman numeral to combine two different symbols: V + I. It opens the additive family that runs from VI through VIII – the five (V) plus one, two or three. After IIII was ruled out and IV introduced subtraction, VI returns to plain, honest addition: one symbol of value 5, followed by one of value 1.

Calculating With VI

• VI + I = VII (6 + 1 = 7)
• VI + IV = X (6 + 4 = 10 – addition merges two numbers into the next symbol)
• VI × II = XII (6 × 2 = 12 – the first product that needs the X)
• XII ÷ VI = II (12 ÷ 6 = 2)
• VI − V = I (6 − 5 = 1)

In mathematics, 6 is the first perfect number: it equals the sum of its divisors (1 + 2 + 3 = 6). It is also the product of those same three numbers (1 × 2 × 3 = 6) – the only number with that property. Its binary form is 110.

Where VI Appears in Real Life

• Monarchs and literature: Henry VI, whose troubled reign Shakespeare turned into a trilogy of history plays.
• Numbered events: Super Bowl VI in January 1972, where the Dallas Cowboys won their first championship.
• Religion: Pope Paul VI, who led the Catholic Church through the reforms of the Second Vatican Council (1963–1978).
• Nature and geometry: the hexagon – six sides – is nature’s favourite shape: honeycombs, snowflakes and basalt columns all form hexagonal patterns.
• Chemistry: the element with atomic number 6 is carbon, the backbone of all known life.

Interesting Fact: In the French Republican Calendar, initiated during the French Revolution, years were numbered by Roman numerals – from the year I (1792) when this calendar was introduced to the year XIV (1805) when it was abandoned.
