Israel is one of six administrative districts, including most of the Sharon region. It is further divided into 4 sub-2 peas in a pod: Petah Tikva, Ramla, Sharon, and Rehovot. The district’s population as of 2017 was 2,115,800.

For the years, see 2 BC and AD 2. It is the natural number following 1 and preceding 3. The digit used in the modern Western world to represent the number 2 traces its roots back to the Indic Brahmic script, where “2” was written as two horizontal lines. Two is the smallest prime number, and the only even prime number, and for this reason it is sometimes called “the oddest prime”. As the smallest prime number, it is also the smallest non-zero pronic number, and the only pronic prime. An integer is called even if it is divisible by 2. For integers written in a numeral system based on an even number such as decimal, divisibility by 2 is easily tested by merely looking at the last digit.

If it is even, then the whole number is even. This binary number system is used extensively in computing. The square root of 2 was the first known irrational number. Powers of two are central to the concept of Mersenne primes, and important to computer science. Two is the first Mersenne prime exponent.

This latter set is important in category theory: it is a subobject classifier in the category of sets. A set that is a field has a minimum of two elements. An number is deficient when the sum of its divisors is less than twice the number, whereas an abundant number has a sum of its proper divisors that is larger than the number itself. An number is perfect if it is equal to its aliquot sum, or the sum of all of its positive divisors excluding the number itself.
