What defines an even number?

• A. Any number that can be divided by 2 without a remainder
• B. Any number that has only one factor
• C. Any number that cannot be divided by 2
• D. An integer that ends with an odd digit

Answer: (A)

An even number is defined as any number that can be divided by 2 without a remainder. This means that when you take an even number and divide it by 2, you will get a whole number, demonstrating that it is evenly divisible. For example, the numbers 2, 4, 6, and 8 are all even numbers because they can be divided by 2 to yield whole numbers (1, 2, 3, and 4 respectively). This definition aligns perfectly with the properties of even numbers in mathematics and is foundational in number theory and arithmetic. When teaching young learners, this concept can help them understand patterns in numbers, recognize sequences, and also solve simple division problems effectively. Understanding that even numbers are multiples of 2 is an important building block in mathematics education, reinforcing foundational skills for future concepts.
