This slide was presented by the Maths Department of Cochin Refineries School for the Inter-School workshop conducted as a part of World Mathematics Day celebration. "Mathematics in day to day life"

3. 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!

4. Maths in Commercial Usage
• Discount
• Banking
• Foreign Exchange
• Stock and Share
• Arithmetic ( Profit & Loss, Percentage, Ratio
and Proportion, Time problem)

5. Discount
Offers during festival seasons.
If you buy Many, get one free/two free.
If you buy for more amount, more discount.

6. Banking
Transaction in Maths
Stocks and Bonds
All these are nothing but Maths!!

7. Foreign Exchange Market
What are the rates of each currency when
compared to Indian Rupees?

8. Stock and Share
 Stocks are sold by Brokers.
The Cost Price = Market value + Brokerage

9. How Algebra is Useful?
Suppose we appoint a person for some work
we give him 2 options:
Say :
i. Rs 100/- per day
ii.Rs 50/- per first day, then increase of Rs 5/-
per the summing days. Which is better?

10. For ex.
i. 30 x 100 = 3000 P.M
ii. 50 + d = S30 = 30 2 x 50 + (30 -1) 5
2
= 15 [ 100 + 29 x 5]
= 15 x 245
= 3675

11. Statistics
• Collection
• Analysis
• Interpretation or Explanation
• Presentation of Data
• Prediction
• Forecasting

12.  Geographical interpretation
 Quality
 Engineering statistics
 Analysis of data from chemistry
 Sports (Cricket/Baseball)
 Statistical survey
 Business statistics

13. 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.

14. Calculus
 It is the study of change
 It 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.

15. Number Theory
It is the branch of pure Maths concerned with
properties of numbers.
It is used for creating codes for ATM/ Credit
Cards.

16. 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

17. Geometry
 Study of shape, size, relative position of
figures with properties of space.
House building
To find the floor area- this is needed for
finding area of carpet or number of tiles.

18. Mechanics
It 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°.

19. NATURE
Sunflower
Seashell- square root of numbers (√1, √2, √3,
√4…)
Fibonacci sequence
The Ancestry of Bees

20. Trigonometry
Help us find the height of a tree.

21. Maths In Biology
SYMMETRY is a general concept of studies in
Science.
Fish Sea Anemone

22. MATHS IN MEDICINE
Reconstruction of the shape of a tumor from
CAT scans and other medical measurements.
Protein modeling etc.
