odd number
A whole number which are not divisible by 2. Example: 1,3,5,7,... are all odd numbers.
Ogive curve:
In statistics, Ogive curve is a graph showing the curve of cumulative distribution function.
One-to-one function
A function from A to B is called one-to-one or 1-1 if whenever f(a)=f(b)then a=b.
Operation
The basic operations in math are addition, subtraction, multiplication and division.
Opposite rays
Opposite rays are two rays that start from a common point and go off in the opposite directions.
Opposite transformation
A transformation that changes the orientation of the figure. Example: Reflection is an opposite transformation.
Order
Sequence of number arranged either in ascending or descending array. Order of a polynomial,order of operations: rules in which the operations should be performed.
Ordered pair:
Two numbers written in certain order (x,y). Usually written in parenthesis. In graph x value represent the number in the x axis and y value represent the number in the y axis. Example: (3,4) is a point whose x coordinate is 3 and y coordinate is 4.
Ordinal number
When objects are placed in order, we use ordinal numbers to tell the position of the number.
Ordinate:
The y coordinate or vertical coordinate of an order pair.
Origin:
A special point usually denoted by 'O' used as a fixed point of reference in geometry. In graph where x and y axes meets, whose coordinates are (0,0).
Orthogonal:
In elementary geometry orthogonal means perpendicular. Two lines or curves are orthogonal if they are perpendicular at their point of intersection.
In vector theory, a set of vectors is called pairwise orthogonal if each pair of them is orthogonal.
Ounce
Ounce abbreviated as oz is a unit of mass equal to 1/16 pound.
We had seen words starting with 'O' in this page math dictionary-O.
“Mathematics, without this we can do nothing in our life. Each and everything around us is math.
Math is not only solving problems and finding solutions and it is also doing many things in our day to day life. They are:
It subtracts sadness and adds happiness in our life.
It divides sorrow and multiplies forgiveness and love.
Some people would not be able accept that the subject Math is easy to understand. That is because; they are unable to realize how the life is complicated. The problems in the subject Math are easier to solve than the problems in our real life. When we people are able to solve all the problems in the complicated life, why can we not solve the simple math problems?
Many people think that the subject math is always complicated and it exists to make things from simple to complicate. But the real existence of the subject math is to make things from complicate to simple.”
