Natural Numbers

Lesson two.

Numbers

when shephers got tired of drop- ping stones, they started to think of other waye to count their propertities. They thus invented systems of numbers. The first syste they invented was the system of " Countine S Numbers

we

This system of numbers includes al possitive while numbers. It begins with the number One" since, when we count always start with one. As we count on, the numbers 2,3,4,5,6,7.

etc. are used All this numbers, make up the number system.. It is easy for us to see that

The order of numbers used for counting is arranged in a way that each number we used is greater tha the previous number by

21 The system never has an end because

it is always possible for us to count up to any number.

This system occurred so naturally ir counting that is is also known as the

Natural Number System

Other Number systems:

[Later ·men found. that the naturai number system is still not very useful. There are still many things that cannot be expressed by using elements of the counting number system. So, as, necessity. demanded. men expanded the natural number system and invented other systems. They are

1) The system of negetive integers, 2) The eystem of real numbere. 3) The system of rational numbere. 4) The system of irrational numbera 5) The aystem of imaginary numbers. 6) The system of complex numbers,

Their relation can be seen in the

The Number Line

Lesson Three

Numbers

f we mark on a straight Line pointe

at equal distances and then at up a one- one correspondence between the set of points on the line and the set of natural number system so that each point on the line is matched with a number in order, then we shall get a line known as the "Number Line”

point.

For the time being let us first coneider the part of the number Line appeare ing at the above. We choose a starting point to start with. We call this point the

zero point" and starting from the zero point, we set up our matching the firet point on the right band side of the Line corresponds: to one the second point cor- responds to two, the third point corresponds and so on. Each point. represente to three,

a number or conversely, every number has a position on the ine.

Fractione can also be placed on the

number

line at corresponding positions.1 This will mean that the number 1 is at a point halfway between the points and 2. The number 23 will have its position at a point three-eighth the dis- tande between the numbers 2 to three, and

so on:

Practions on number line

Direction of numbera

It is understood that the numbers appearing to the right hand side of zero are poaitive numbers and numbers appearing to the left hand side of yero are negetive numbers. All positive numbers are preceeded by the eiga + Thus +7 meane a point at 7 unite to the right of zero on the number line, All negetive numbers are preceeded by the sign Thus -5 is the point at 5 unit distance te the left of the zero point. If a number is not preceeded by any sign, it is understood to be positive. The positive numbers and th negetive numbers make up the whole number line is drawn out in the following figure, Here, the zero point is placed at the middz. and is also known as the..." Origin
