Every subject in school, whether you are in elementary or high school and even college there is a lesson concerns with how to identify a number or what type of classification it is. There is always a set of numbers on how to group it together. People are very familiar of what we call the real number line. It is a line that divided up in a little bit pieces. What is amazing about number line is there is a direct correspondence between numbers.

Natural numbers are the numbers that you can count on the number line. For example you count from one to ten. Among these numbers one is the smallest natural number. Sometimes, it was asked during test in schools. The national numbers are fine for counting, but we are missing a very special number which we need to take consideration and that is the number zero. Zero number has also it’s corresponding point on the number line. The collection of number within the number line is called whole number. The math symbol for zero is W and it is the smallest whole number that you have.Be aware that there is no largest whole number that goes on forever.

Integers are also whole numbers. You can do quite a bit with them. For example you count the big bucks from one to twenty, then that is great but for example if you look any your bank accounts recently and you do not see any of these things like a number and it’s negative value that is called value. Value that are less than zero on a number line is called the integer. The symbol for integer is Z. It is traditionally denoted with the letter Z. Note, if you have the problem grasping the concept of a negative number just think of it as a debt.

These are some of the basic lessons in Math. Probably, the subject depends on the level or degree you are studying. Math is everywhere and is needed in our daily life.
