In mathematics, some words often confuse students; a good example of this is the difference between “prime numbers” and “aggregated numbers.” It can be complicated for some, but in reality, it is very easy. It all has to do with the concept of natural numbers and the characteristics of which we all know. Students will be informed of the terms as soon as they reach the end of the article.

prime numbers

By natural numbers, singular to infinite, [1, 2, 3, 4, 5… infinity]; those numbers that can have only two elements, one number 1 and the other number itself, are called prime numbers. Simply put, those numbers can be divided by only 1 and are themselves called prime numbers. So they have only two dividers.

For example:

3 (features 1 and 3);

7 (features 1 and 7), etc.

So when calculated, the key numbers are endless.

[2, 3, 5, 7, 11, 13, 17, 19… endless]

Key numbers are always odd numbers, except for 2, because if they were equal, they would be divided by 2 which is not the property of the main numbers.

Composite numbers

All numbers except the main numbers, except 1, are integers because they have more than two elements. That is, aggregated numbers can be divided by 1, themselves, and other numbers as well.

For example:

4 (features 1, 2 and 4);

20 (features 1, 2, 5 and 20), etc.

Here again, we have endless combined numbers.

[2, 4, 6, 8, 9, 10, 12, 14, 15… endless]

Combined numbers may or may not be equal depending on their characteristics. If it has at least one number, it will be the same number. If it doesn’t even have a number in its numbers, then it will be an odd number.

The number 1 by natural numbers varies as this number cannot be divided as the first or plus number.
