Maths and Fun: even and Odd

even and Odd

Even numbers will be divided equally into teams of 2. the amount four will be divided into 2 teams of 2.
Odd numbers can't be divided equally into teams of 2. the amount 5 will be divided into 2 teams of 2 and one cluster of 1.
Even numbers forever finish with a digit of zero, 2, 4, 6 or 8.

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, thirty square measure even numbers.

Odd numbers forever finish with a digit of one, 3, 5, 7, or 9.

1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, thirty one square measure odd numbers.

Adding Even and Odd Numbers

even + even = even

4 + 2 = 6

even + odd = odd

4 + 3 = 7

odd + odd = even

5 + 3 = 8

Subtracting Even and Odd Numbers

even - even = even

4 - 2 = 2

even - odd = odd

4 - 3 = 1

odd - odd = even

5 - 3 = 2

Multiplying Even and Odd Numbers

even x even = even

4 x 2 = 8

even x odd = even

4 x 3 = 12

odd x odd = odd

5 x 3 = 15

Division, or The Fraction downside

As you'll see, there square measure rules that tell what happens once you add, subtract, or multiply even and odd numbers. In any of those operations, you'll forever get a selected quite number.

But once you divide numbers, one thing tough will happen—you may be left with a fraction. Fractions aren't even numbers or odd numbers, as a result of they're not whole numbers. they're solely elements of numbers, and might be written in numerous ways in which.

For example, you cannot say that the fraction 1/3 is odd as a result of the divisor is associate degree odd range. you'll even as well write that very same fraction as 2/6, during which the divisor is a good range.

The terms “even number” and “odd number” square measure solely used for whole numbers and their opposites (additive inverses).
