Arithmetic Number[edit]

Natural number The numbers which are generally used in our day to day life for counting are
termed as natural numbers. They are also referred to as "counting" numbers
Even number Number divides by 2 without remainder . Even number is denotes as 2N
Odd number Number divides by 2 with remainder Odd number is denotes as 2N+1
Prime number Number divides by 1 and itself without remainder . Prime number is denoted as P
Integer Signed numbers
Complex Number number made up of real and imaginary number
Imaginary Number

Arithematic Function[edit]


Function is an arithmetical expression which relates 2 variables . Function is denoted as

meaning for any value of x there is a corresponding value y=f(x)


x - independent variable
y - dependent variable
f(x) - function of x

Graph of function[edit]

x -2 -1 0 1 2
f(x) -2 -1 0 1 2
Straight line passing through origin point (0,0) with slope equals 1

x -2 -1 0 1 2
f(x) -4 -2 0 2 4
Straight line passing through origin point (0,0) with slope equals 2

x -2 -1 0 1 2
f(x) -1 1 3 5 7

Straight line with slope equals 2 has x intercept (-3/2,0) and y intercept (0,3)

Arithmetic Equation[edit]

An arithmetic equation is an expression of a function of variable that has a value equal to zero

Arithmetic equations can be solved to find the value of variable that satisfies the equation. The process of finding this value is called root finding. All values of variable that make its function equal to zero are called roots of the equation.


Equation .
Root .
is the root of the equation since substitution the value of x in the equation we have
