Andrea Bender and Sieghard Beller at the University of Bergen in Norway studied the Mangarevan language, which dates back to AD 1500, or even earlier. The pair say that, as in the decimal system ...

But for numbers 20 through 80, they used a binary system, with separate, one-word terms for 20, 40 and 80. For really large numbers, they used powers of 10 up to at least 10 million.

Our number system is a decimal system, ... For example, at the moment the ... or bits, corresponds with an octal digit. The binary 010 translates into 2, and 110 translates into 6.

Binary is a number system that only uses two digits, ... The decimal number system, which we use everyday, ... Add the numbers in the binary place value row that have a 1 in the binary row; Example.

They find that the former Mangarevans combined base-10 representation with a binary system. They had number words for 1 to 10, and then for 10 multiplied by several powers of 2.

Unlike our everyday counting system that uses tens, binary uses just two numbers, 0 and 1. Learn more with BBC Bitesize. Suitable for KS3 students.
