What is an Integer?
Integers are whole numbers that can be positive, negative, or zero. In mathematics, the set of integers is denoted by ℤ. They are the foundation of number theory and modular arithmetic.

Pro Tips
Even/Odd: An integer is even if it is divisible by 2, and odd otherwise.
Primes: A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Zero: Zero is an even integer because 0 = 2 × 0.

Fun Facts
"The number 1 is neither prime nor composite."
"Every integer greater than 1 has a unique prime factorization (Fundamental Theorem of Arithmetic)."
"Perfect numbers are integers that equal the sum of their proper divisors (e.g., 6, 28)."
