Once
upon a time, zero wasn’t really a number. Its journey to the fully
fledged number we know and love today was a meandering one. Today, zero
is both a placeholder, and tool, within our number system signifying an
absence of a value, and as a number in its own right.

But it
wasn’t always seen as that, and it still doesn’t act quite like other
numbers. Can you divide by zero, for example? Hannah Fry explains how
zero came about, from its origins in ancient civilisations, through the
resistance it faced from the Roman numeral system, to being the
cornerstone of calculus.
