What is the term for a number that can be divided by 2 without a remainder?

• A. Odd number
• B. Even number
• C. Composite number
• D. Prime number

Answer: (B)

A number that can be divided by 2 without a remainder is termed an even number. An even number is defined as any integer that can be expressed in the form 2n, where n is an integer. When you divide an even number by 2, it results in a whole number, hence there is no remainder. In contrast, odd numbers are defined as integers that cannot be evenly divided by 2, resulting in a remainder of 1. Composite numbers refer to integers that have factors other than 1 and themselves; they can be even or odd. Prime numbers are defined as numbers greater than 1 that have no positive divisors other than 1 and themselves; they can also be either even (the only even prime is 2) or odd. Understanding these distinctions helps in recognizing the unique properties of even numbers.
