Even number facts for kids

An even number is a number that can be divided by two into two equal parts, with no remainder left over. Think of it like sharing candies equally between two friends – if you have an even number of candies, everyone gets the same amount! Numbers like 2, 4, 6, 8, and 10 are all even numbers. A quick trick to spot an even number is to look at its last digit: if it ends in 0, 2, 4, 6, or 8, it's an even number.

If a number is not even, it's called an odd number. When you divide an odd number by two, you'll always have a remainder, meaning it can't be split into two perfectly equal groups.

What Makes a Number Even?

A number is considered even if it fits a simple rule: it must be a whole number (not a fraction or decimal) and it must be perfectly divisible by 2. This means that when you divide an even number by 2, the answer is another whole number, and there's nothing left over.

For example:

• 6 divided by 2 equals 3 (a whole number, no remainder). So, 6 is an even number.
• 10 divided by 2 equals 5 (a whole number, no remainder). So, 10 is an even number.

Even Numbers vs. Odd Numbers

Even and odd numbers are like opposites!

• Even numbers can always be paired up perfectly. Imagine you have 8 socks; you can make 4 pairs with no socks left alone.
• Odd numbers always have one left over when you try to pair them up. If you have 7 socks, you can make 3 pairs, but one sock will be all by itself.

When you divide an even number by 2, the result is always another whole number. But if you divide an odd number by 2, you'll get a number with a decimal, like 3.5 or 7.5.

Can Negative Numbers Be Even?

Yes, they can! Since even numbers are integers (which include positive numbers, negative numbers, and zero), negative numbers can also be even. For example, -2, -4, -6, and -8 are all even numbers because they can be divided by 2 with no remainder.

Cool Facts About Even Numbers

• Multiplying with Even Numbers: If you multiply any even number by any other number (whether it's even or odd), the answer will always be an even number.

* Example: 4 (even) × 3 (odd) = 12 (even) * Example: 6 (even) × 8 (even) = 48 (even)

• Adding and Subtracting:

* Even + Even = Even (e.g., 2 + 4 = 6) * Even - Even = Even (e.g., 10 - 4 = 6) * Even + Odd = Odd (e.g., 2 + 3 = 5) * Even - Odd = Odd (e.g., 8 - 3 = 5)
