Maths in Day to Day Life
Maths is all around us, it is everywhere we go.
Not only does Maths underline every process and pattern that occurs in the world around us, but also, a good understanding of it will help enormously in our every day life.
Being fast in Mental arithmetic can save your money when you go to market!

How Algebra is Useful?
Suppose we appoint a person for some work we give him 2 options:
Say :i. Rs 100/- per dayii.Rs 50/- per first day, then increase of Rs 5/-
per the summing days. Which is better?
For ex.i. 30 x 100 = 3000 P.Mii. 50 + d = S30 = 30 2 x 50 + (30 -1) 5
2 = 15 [ 100 + 29 x 5] = 15 x 245 = 3675
Statistics
• Collection • Analysis• Interpretation or Explanation• Presentation of Data• Prediction• Forecasting
Geographical interpretation Quality Engineering statistics Analysis of data from chemistry Sports (Cricket/Baseball) Statistical survey Business statistics
How the concept of Mean, Median & Mode are used in daily life?
A shopkeeper keeps more stock of a particular type of shoe which has more sale. Here the concept of MODE applies.
The average daily expenditure in a month of a family gives the concept of MEAN.
If 15 people of different heights are standing height-wise, then the middle man’s height is the MEDIAN height.
Calculus
It is the study of changeIt includes limits, derivatives, integrals and
infinite series.It helps us to find the area of figures, to know
the acceleration of a car moving in a highway with a uniform speed. Also, the movement of an artificial satellite, ship etc.
Number Theory
It is the branch of pure Maths concerned with properties of numbers.
It is used for creating codes for ATM/ Credit Cards.
Graph Theory
It is the study of graph.To find the easy route that can be used by a
sailor from one port to another.
The best way to reach all the port is shown by the arrows
Geometry
Study of shape, size, relative position of figures with properties of space.
House buildingTo find the floor area- this is needed for
finding area of carpet or number of tiles.
MechanicsIt is concerned with the behaviour of physical
bodies subject to forces or displacements.For example: Maximum distance a football can
go when kicked by the goal keeper at an angle of 45°.
