The number six is **a natural number that comes after the number five and before the number seven**. Six is also the first perfect number which means that the sum of its factors (1, 2 and 3) are equal to the number itself (6).

Is 0 a Natural Number? Zero does not have a positive or negative value. **Since all the natural numbers are positive integers**, hence we cannot say zero is a natural number. Although zero is called a whole number.

'**No,' 0 is not a Natural number**. Natural numbers, as we know, are positive integers that span from 1 to infinity. However, once we combine 0 with a positive integer like 10, 20, or the other number, we get a number.

One, sometimes referred to as unity, is **the first non-zero natural number**. It is thus the integer after zero. Any number multiplied by one remains that number, as one is the identity for multiplication. As a result, 1 is its own factorial, its own square and square root, its own cube and cube root, and so on.

**A ternary /ˈtɜːrnəri/ numeral system (also called base 3 or trinary) has three as its base**. Analogous to a bit, a ternary digit is a trit (trinary digit). One trit is equivalent to log_{2} 3 (about 1.58496) bits of information.

About 773 AD the mathematician **Mohammed ibn-Musa al-Khowarizmi** was the first to work on equations that were equal to zero (now known as algebra), though he called it 'sifr'. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.

International Numeral System. **The place values of digits go in the sequence of Ones, Tens, Hundreds, Thousands, Ten Thousand, Hundred Thousands, Millions, Ten Million and so on**, in the international numeral system.

Natural Numbers (N), (also called positive integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …} **Whole Numbers** (W). This is the set of natural numbers, plus zero, i.e., {0, 1, 2, 3, 4, 5, …}.

perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. **Other perfect numbers are 28, 496, and 8,128**.

It is a prime number.

Seven is considered by some to be the most 'prime' number within the first 10 numbers as **you cannot multiply it within the group**, making it a kind of optimal-prime (not to be confused with Optimus Prime, who is a Transformer).

Gottfried Leibniz's major contribution to mathematics was his **discovery of the binary numeral system**, or the base-2 system, which we find today in computers and related devices. The binary numeral system is a way of writing numbers using only two digits: 0 and 1.

**One million** (1,000,000), or one thousand thousand, is the natural number after 999,999 and before 1,000,001.
