Answer . Because he considers them as units,not numbers By his definition,units are indivisible in quantity. (see Aristotle and maths,Stanford encyclopedia of Philosophy)
Answer . There would no longer be a unique prime factorization for positive integers - for example, 12 could be expressed as both 2*2*3, 1*2*2*3, or 1*1*1*1*2*2*3, or any other number. A lot of mathematical proofs that depended on this property, or a number of other properties of prime numbers, would have to be rewritten. Inevitably, someone would come up with some other definition, such as "prime rib numbers", which would be defined as "prime numbers not including 1", and then people would start using these "prime rib numbers" instead. \n. \nThe definitions in mathematics are anything but arbitrary - all of them have been introduced for a reason. It's possible to make up your own definitions, but unless there were a good reason to use them, no one would accept them - the fact that every mathematician knows what a prime number is means that the definition of prime numbers is a good one.
Answer . The purest.
\nit is a unit.

because its not prime or composite
It is a negative integer, a rational, a real.
No, and neither are 0 or 1.
A prome number (1, 5, 7, 11, 13, 17, 19 etc.) divisible only by itself and 1.
1 was considered as a prime but now the definition changed. Now the definition was that a prime is divisible only by 1 and itself
PRIME NUMBERS are numbers that is divisible by itself and 1
Those are prime numbers.
In no order, and not including the Greek and Arabic classical mathematicians: Abel Gauss Euler Descartes Riemann Leibniz Newton Turing
It depends on what the subset is of.
In mathematics, the number two has several properties. For instance, an integer is considered even if it is able to be divided by two. Also, the square root of two was the first-ever irrational number. Another property of the number two is that the number is highly composite, meaning that it contains more divisors than the number one.
Because a prime number has two factors whereas 1 has only one factor which is itself
In number theory , the fundamental theorem of arithmetic , also called the uniquefactorization theorem or the unique-prime-factorizationtheorem , states that every integer greater than 1 either is prime itself or is the product of prime numbers , and that this product isunique, up to the order of the factors. For example, . 1200 = 2 4 Ã 3 1 Ã 5 2 = 3 Ã 2 Ã 2Ã 2 Ã 2 Ã 5 Ã 5 = 5 Ã 2 Ã 3 Ã 2 Ã 5 Ã 2 Ã 2 = etc. . The theorem is stating two things: first, that 1200 can be represented as a product of primes, and second, no matter howthis is done, there will always be four 2s, one 3, two 5s, and noother primes in the product. . The requirement that the factors be prime is necessary:factorizations containing compositenumbers may not be unique (e.g. 12 = 2 Ã 6 = 3 Ã 4). . This theorem is one of the main reasons for which 1 is notconsidered as a prime number: if 1 were prime, the factorizationwould not be unique, as, for example, 2 = 2Ã1 = 2Ã1Ã1 = ...
Algebra makes use of letters and mathematical symbols.
If you mean integers of 1 and 2 then it is 0
