Number system
? In earlier days, people used to exchange their things for
other things. The requirement for numbers primarily
originated from the need to count.
? They used the numbers 1,2,3,.that served the people for
many years because all they needed to count was their
crops, and animals.
? Later on numbers such as zero, integers, rational
numbers, irrational numbers were introduced.
? There is evidence that as early as 30,000 BC our ancient
ancestors were tallying or counting things. That is where
the concept of number systems began.

Numbers
? Natural Numbers:
?A natural number is a number that comes naturally,
?Natural numbers are greater than zero we can use this
numbers as  counting numbers:  {1, 2, 3, 4, 5, 6 ….…, }.
? Whole numbers:
?Whole numbers are just all the natural numbers plus a
zero: {0, 1, 2, 3, 4, 5, ……………… , }.
? If our system of numbers was limited to the Natural
Numbers then a number such as –2 would have no
meaning.  The next number system is the Integers.

?Integers include the Natural numbers, zero, and the
negative Natural numbers.
?Numbers in the form of negative and positive numbers  {

? Rational number:
?Which can be written in the form of       .
?Where p and q are integers and q ? 0 is called a rational
number, so all the integers  are rational number .
