- 2. A numeral system (or system of numeration) is a writing system for expressing numbers, that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner.
- 3. The Natural Numbers are those used for counting. Properties of the natural numbers related to divisibility. There is no universal agreement about whether to include zero in the set of natural numbers.
- 4. Whole numbers are easy to remember. The only thing that makes them different than natural numbers is that we include the zero Whole numbers are 1, 2, 3, 4, and mire
- 5. Rational numbers have integers AND fractions AND decimals. Now you can see that numbers can belong to more than one classification group. Rational numbers can also have repeating decimals
- 6. Integers can be whole numbers or they can be whole numbers. Whole numbers with a negative signs in front of them. Individuals often refer to integers as the positive and negative numbers.
- 7. However, irrational numbers can have a decimal value that continues forever WITHOUT a pattern Irrational numbers don't include integers OR fractions. An example of a well known irrational number is pi which as we all know is 3.14 but if we look deeper at it, it is actually 3.14159265358979323846264338327950288419.....and this goes on for somewhere around 5 trillion digits!
