Integers:
Integers are whole numbers: positive numbers, negative numbers and zero. When you add two integers together you will always get an integer as the result. However dividing two integers could end in a non-integer.
The integer was introduced in the year 1563 when Arbermouth Holst was busy with his bunnies and elephants experiment. He kept count of the amount of bunnies in the cage and after 6 months he found the amount of bunnies increased. Then he thought of inventing a number system of adding and multiplication. He spent 15 years developing this number system.
Then in 1890 Japanese mathematicians worked on it and created ‘integers’. A latin word meaning “untouched”.
The symbol for integers is a ‘Z’ because of ‘Zahlen’, the German word for integers or number.
Zero was invented independently by the Babylonians, Mayans and Indians. (Although some researchers say that the Indian number system was influenced by the Babylonians.)
There was an Indian Hindu mathematician who is said to have first endorsed the number “zero”. Prior to its “official” creation, no other countries used the number until it reached Indian subcontinent.
Before the zero was used, the thing that mathematicians utilized was black spaces to decide how to calculate a problem as if there was nothing there.
Negative numbers were finally accepted into the number system in the 19th century. Negative numbers were found to be useful solving tricky equations like cubic and quartic equations.
Indians:
The Indian mathematician Brahmagupta is known to have used negative numbers starting around 630 AD. During this time, positive numbers were used to represent assets and negative numbers were used to represent debt.
Chinese:
The Chinese are credited with being the first known culture to recognize and use negative numbers. They used red rods to represent negative numbers.
Europe started using negative numbers in 1545.
Before any number system was created people used rocks, sticks or counted on their fingers. There was an Italian mathematician by the name of Girolamo Cardano, who described negative numbers as ‘fictitious’ and accepted the possibility of them being useful.
