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)
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°.
