Let us learn about "numeral system commonly"
A numeral is a symbol or group of symbols that represents a number. Numerals differ from numbers just as words differ from the things they refer to. The symbols "11", "eleven" and "XI" are different numerals, all representing the same number. This article treats the various systems of numerals. See also number names.
A numeral system (or system of numeration) is a framework where a set of numbers are represented by numerals in a consistent manner. It can be seen as the context that allows the numeral "11" to be interpreted as the Roman numeral for two, the binary numeral for three or the decimal numeral for eleven.
A number system is a set of objects on which arithmetic operations can be performed.
The most commonly used system of numerals is known as ... system still in common use. The unary system is only useful for small numbers ... base, we write a number in the numeral system
Roman numerals are a numeral system of ancient Rome based on letters of the alphabet, which are combined to signify the sum of their values. The Roman numeral system is decimal but not directly positional and does not include a zero. The Roman numeral system is written by letters. The letter may be in either upper or lower case
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000

A plot chart shows changes over a period of time by drawing a continuous line from one data point to the next, one data point for each data sampling and one line for each attribute selected.
A chart of line plot shows that a data on a given number line with variable x or to represents the frequency. A group of data can be given, in that data should be marked on the line chart. Plot the line chart can be very easy to use and plot the line chart with sufficient data given.
Description to Line Plot Chart:
There are some rules for line plot chart, they are
Rules for line plot chart:
Read out the whole given data.
Find out like terms in the given data.
Start from marking the least to highest data given.
Start marking the same data above the line chart one by above.
Then finish marking the data up to the last level vice versa.

A graph consists of a set of nodes represented by small circles, and a set of arcs represented by lines. If a path can be found that connects all the nodes, then a graph is said to be a connected graph. If no pair of nodes is connected by more than one arc then the graph is said to be a simple graph. A graph in which each arc has an associated direction is a digraph.
There are different types of graph in the graph theory.They are given below with an example for each. In the graph theory applications we use these all the
Types of Graphs.
1. Simple Graph
2. Multiple Graphs
3. Pseudo graph
4. Null Graph
5. Finite graph
6th Types of Graph: Regular Graph

Let us know which are the numeral most commonly used.
Some numerals in common use are given below:
Indian numerals - Most of the positional base 10 numeral systems in the world have originated from India, which first developed the concept of positional numerology. The Indian numeral system is commonly referred to in the West as the Hindu-Arabic numeral system or even Arabic numerals, since it reached Europe

Numerical prefix - Numerical prefixes are prefixes usually derived from the words for numbers in various languages, most commonly Greek and Latin, although this is not always the case. Because of the common inheritance of Greek and Latin roots across the Romance languages, the import of much of that derived vocabulary
Rules of Writing Roman Number
Some rules are used in Roman number numeral system, these rules are explaining below:
(1) Multiplication Rule: If a symbol is repeated in succession, the value of the numeral is obtained by multiplying the value of the symbol by the number of times is repeated. No symbol is repeated more than three times.
Examples:
II = 1x 2 = 2
111 = 1 x 3 = 3
XX = 10 x 2 = 20
XXX = 10x3 = 30
CCC = 100x 3 =300
(2) Addition Rule: When a smaller number is written on the right of a bigger number, the smaller number is added to the bigger number.
Examples: V111 = 5 + 1 + 1+1 = 8
XX11 = 10 + 10 + 1 + 1 = 23
CX X = 100 +10 + 10 = 120
(3) Subtraction Rule: When a smaller number is written on the left of the bigger number the smaller number is subtracted from the bigger number.
Examples: 1V = 5 - 1 = 4
CM = 1000 -100 =900
XL = 50 -10 = 40
XXC = 100 – 20 = 80
Important points for writing Roman numeral number system:
(a)The symbol 1 can be subtracted only from V and X.
(b) V, L, D are never subtracted.
(c)The symbol X can be subtracted only from L and C.
(d)The symbol C can be subtracted D and M once only.
(e)There is another symbol ___ called bar. It is placed over a numeral which is multiplied by1, 000.

The area of a triangle is the distance enclosed by its sides. A three-sided polygonis called a triangle.
To find the area of a triangle we need to multiply the base by the height, and then divide by 2. Here we are dividing because we know that aparallelogram can be divided into 2 triangles. You can observe from the given figure below that the area of each triangle is equal to one-half the area of the parallelogram.
As we know that the area of a parallelogram is Area = base x height so, the area of a triangle must be equal to one-half the area of a parallelogram.
Therefore, the area of a triangle = 1/2 x base x height.

An equation which consists of more than one terms are squared but no higher power in terms, having the syntax, ax2+bx+c where a represents the numerical coefficient of x2, b represents the numerical coefficient of x, and c represents the constant term
Example: x2- 9x+12
A quadratic function, in mathematics, is a polynomial function of the form f (x) = ax2 + bx + c , a ≠ 0.The graph of a quadratic function is a parabola whose major axis is parallel to the y-axis. The expression ax2 + bx + c in the definition of a quadratic function is a polynomial of degree 2 or second order, or a 2nd degree polynomial, because the highest exponent of x is 2.If the quadratic function is set equal to zero, then the result is a quadratic equation. The solutions to the equation are called the roots of the equation
