Mathematics is present in many aspects of daily life. It underlies processes that occur in the world and can help with tasks like mental arithmetic to save money. Math is used in commercial activities like discounts, banking, foreign exchange, stock prices, and calculations involving profit/loss, percentages, ratios, and time. Algebra can help determine which payment option is better for a job. Statistics are used to collect, analyze, interpret, present, predict, and forecast data. Concepts like mean, median, and mode help in areas like determining average daily expenditures or keeping optimal stock levels. Number theory and geometry have applications in coding, construction, and calculating areas. Mathematics also aids fields like biology, medicine, and modeling.

2. 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!

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

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

5. Banking

Transaction in Maths.

Stocks and Bonds
All these are nothing but Maths!!

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

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

8. 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?

9. 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. 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

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

13. 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.

14. Maths In Biology

SYMMETRY is a general concept of
studies in Science. Fish Sea & Anemone

15. MATHS IN MEDICINE


Reconstruction of the shape of a tumor
from CAT scans and other medical
measurements.
