What are even and odd numbers?

Even numbers are whole numbers divisible by 2 with remainder 0 (2, 4, 6, 8, ...). Odd numbers leave remainder 1 when divided by 2 (1, 3, 5, 7, ...).

How many even and odd numbers are there from 1 to 1000?

There are 500 even numbers and 500 odd numbers from 1 to 1000. In every block of 100 numbers there are exactly 50 of each.

How can you tell if a number is even or odd quickly?

Look at the last digit. If it is 0, 2, 4, 6 or 8 the number is even; if it is 1, 3, 5, 7 or 9 the number is odd. This works for any size of number.

0 is even, because it is divisible by 2 with remainder 0 (0 = 2 x 0). It sits between the odd numbers -1 and 1.

What is the sum of all even and odd numbers from 1 to 1000?

The even numbers add up to 250,500 (n(n + 1) with n = 500) and the odd numbers add up to 250,000 (n^2 with n = 500). The evens exceed the odds by 500.

What happens when you add or multiply even and odd numbers?

Even + Even = Even, Odd + Odd = Even and Even + Odd = Odd. For multiplication, Odd x Odd = Odd and any product with an even factor is even.

Frequently Asked Questions

Question	Answer
What are even and odd numbers?	Even numbers are whole numbers divisible by 2 with remainder 0 (2, 4, 6, 8, ...). Odd numbers leave remainder 1 when divided by 2 (1, 3, 5, 7, ...).
How many even and odd numbers are there from 1 to 1000?	There are 500 even numbers and 500 odd numbers from 1 to 1000. In every block of 100 numbers there are exactly 50 of each.
How can you tell if a number is even or odd quickly?	Look at the last digit. If it is 0, 2, 4, 6 or 8 the number is even; if it is 1, 3, 5, 7 or 9 the number is odd. This works for any size of number.
Is 0 even or odd?	0 is even, because it is divisible by 2 with remainder 0 (0 = 2 × 0). It sits between the odd numbers -1 and 1.
What is the sum of all even and odd numbers from 1 to 1000?	The even numbers add up to 250,500 (n(n + 1) with n = 500) and the odd numbers add up to 250,000 (n² with n = 500). The evens exceed the odds by 500.
What happens when you add or multiply even and odd numbers?	Even + Even = Even, Odd + Odd = Even and Even + Odd = Odd. For multiplication, Odd × Odd = Odd and any product with an even factor is even.
