Do you know what numeric sets are? You numerical sets are groups of numbers that have more than one feature in common.
Each numeric set has subsets, which is an additional way to separate numeric groups. For example, the whole number set has as a subset the pair numbers and odd.
The set of whole numbers is made up of non-decimal numbers, known as non-comma numbers. These are the units that are not yet shared. This set has both negative and positive numbers, as well as zero.
In addition, the set of natural numbers is also present in whole numbers, as these are integers and not negative, that is, the set of natural numbers is a subset of the integers.
After this brief introduction to number sets, find out now what the odd and even numbers.

the even numbers are one
subset of integers. One way to discern the even number is knowing that it always ends with 0, 2, 4, 6 or 8. Also, every even number is multiple and divisible by 2.Some even number examples they are:
- 4 – (4/2 = 2);
- 10 – (10/2 = 5);
- 22 – (22/2 = 11);
- 48 – (48/2 = 24);
- 222 – (222/2 = 111);
- 448 – (448/2 = 224).
Odd numbers
Odd numbers are a subset of integers that are not even. These numbers end with 1, 3, 5, 7 or 9. Every subset of odd numbers is not multiple or divisible by 2.
Some odd number examples they are:
- 5 – (5/2 = 2,5);
- 11- (11/2 = 5,5);
- 23 – (23/2 = 11,5);
- 49 – (45/2 = 24,5);
- 223 – (223/2 = 11,5);
- 449 – (449/2 = 224,5).
