**Know Your
Numbers: The Basics.**
In mathematics,
you'll see many references about numbers. Numbers can be classified
into groups and intially it may seem somewhat perplexing but as you
work with numbers throughout your education in math, they will soon
become second nature to you. You'll hear a variety of terms being
thrown at you and you'll soon be using those terms with great
familiarity yourself. You will also soon discover that some numbers
will belong to more than one group. For instance, a prime number is
also an integer and a whole number. Here is a breakdown of how we
classify numbers:
**
Natural Numbers**
Natural numbers are what you use when you are counting one to one
objects. You may be counting pennies or buttons or cookies. When you
start using 1,2,3,4 and so on, you are using the counting numbers or
to give them a proper title, you are using the natural numbers.(Resource)
**
Whole Numbers**
A whole number is a number denoting one
or more whole things. It can be contrasted with a fraction, which is
a number that is used to denote quantities including part of a unit.
Whole number is also called integer. However it is more common to
use the term whole number in relation to fraction. A whole number is
a number that does not contain a decimal. In addition to this, it
does not contain any negative numbers at all. If they did contain
negative numbers then they would be considered integers. Examples of
whole numbers are 0, 1, 2, 3, 4, and so on. So just remember, whole
numbers means there are no fractions or negative numbers. All
counting numbers are also whole numbers except for 0. Counting
numbers are 1, 2, 3, 4, 5, 6, and so on.(Resource). |
