Roman Numbers

In the previous post we have discussed about multiplication of whole numbers
 and In today's session we are going to discuss about Roman Numbers. Roman numbers are number representation system which uses a combination of letters to represent any numerical value. Roman numbers are the numbers which discovered from the ancient roman period. Roman numbers are the combination of Latin alphabets which is popularly used for to signify the values. Roman numerals are special kind of number representing system which has an additive system of letter popularly used for base value numbers. Roman numbers or values are not directly positioned and they do not have any symbol for  representing a value of zero. (know more about Roman Numbers, here)

In the below we show some of the symbol that help us in forming other roman values:

Symbol => I    V    X    L       C          D      M

 Value    =>1    5    10   50    100    500  1000

The roman numbers can be formed by adding symbol together that will generate a new value. Now we show some of basic combination of roman numbers from one to ten that are given below:

Number =>            1    2    3    4    5    6    7    8      9   10  

Roman no. =>        I    II   III    IV   V   VI  VII  VIII  IX    X

Now we show some of pattern that helps you in understanding the concept of Roman Numbers:

Suppose we want to represent a number 40 in the form Roman numeral now we need to process this thing step by step. Let’s show you below:

 As given that value of 50 = L

Then we need required 40 then = 50 – 10 = 40

It means that                                 = L – X = XL

In the same aspect we want to represent value of 60 then

As given that value of 50 = L

Then we need required 60 then = 50 + 10 = 60

It means that                                 =  L + X = LX

In mathematics, the Surface Area of Rectangular Prism can be describe by using the concept of rectangle that are given below:

 2 * Length * Width  + 2 * (Length + Width )* Height

multiplication of whole numbers

In the previous post we have discussed about display and In today's session we are going to discuss about multiplication of whole numbers. Whole number can be defined as all the number greater than equal to zero. In the whole number fraction number and negative number are not involved. For example: 0, 10, 21, 30, 45, 500, 61, 704, 8025, 901254 and so on are all are included in whole number. And also decimal numbers are not included in case of whole number. Now we will see how to perform multiplication of whole numbers. We need to follow some steps to the multiplication of whole number. The steps are shown below:
Step 1: To the multiplication of whole number first of all we have to take two or more than two values.
Step 2: Then multiply one term to the whole value of the other term.
Step 3: Apply these procedure till the last value.
Step 4: And if we have three values then first we have to multiply two values than the result we get is multiplied by the next value to get the required result. (know more about Whole number, here)
Step5: If we apply the above procedure carefully then we get the result.
Suppose we have two values 150 and 20, then we have to multiply both the values.
Solution: To perform the multiplication over the given values first clear that the given values are whole number or not. So here the given numbers are 150 and 20. According to the definition of whole number the given number follow the property of whole number. Now write the number in the multiplication form:
⇨ 150 * 20, if we multiply the number 0 to the next whole digit then we get 0, so we can write it as:
150
  20
000,
Then we apply same procedure to the next digit. On multiplying we get:
150
  20
  000,
300 X
3000
So, the multiplication of two numbers we get is 3000. This is how we can perform multiplication over the whole number. Now we will see the Vertex of a Parabola, as we know that no vertices are present in a parabola because it has curve shape. To get more information about these then prefer online tutorial of icse syllabus for class 8.

When we observe that many collinear points are joined together to form a line, this line goes endlessly in both the directions and has no fixed endpoints. So we say that the line extends endlessly in both the directions and so it does not have any fixed length. We say that the pair of lines, when intersect each other, so that they  meet each other at only one point, then we say that the two lines are intersecting Also we  say the meeting point of these two intersecting lines as the point of intersection.
Now we will learn what is a Perpendicular Line?
 If we have a pair of intersecting lines such that the angles so formed at the point of intersection of the two lines is 90 degrees then we say that the pair of lines are Perpendicular Lines
If we look at the + sign, it shows that the two lines are perpendicular. The English alphabets: L, T, H F and E are formed by joining two or more perpendicular lines.
Also we know that if the two angles which are supplementary to each other are joined as the adjacent angles, then the pair of such angles, formed the  pair of perpendicular lines  by their uncommon arms.
In on a straight line a perpendicular line is drawn, we say that two angles of 90 degrees is formed. So we say that a perpendicular line drawn on the straight line divides the line into two equal angles of 90 degrees each.
Also if we look around us in our daily life examples, we say that the edge of the wall, edge of the table and many such objects forms a pair of perpendicular lines.
