This document discusses various applications of math in daily life. It covers topics like ratios, proportions, geometry, savings, interest, exponential growth, and how math helps us understand concepts like population growth. Ratios are used in cooking and other areas. Geometry formulas are used to calculate area and other spatial properties. Savings and interest are explained using formulas for simple and compound interest. Exponential growth follows predictable patterns seen in population increases and other natural phenomena. Overall, the document illustrates how math underpins many aspects of daily life and decision making.

2. IntroductionIntroduction
When we buy a car, follow a recipe, or
decorate our home, we're using math
principles.
Human beings didn't invent math concepts;
we discovered them
The language of math is numbers, not English
or German or Russian.
Math can help us to shop wisely, buy the
right insurance, remodel a home within a
budget, understand population growth etc.

3. Maths have many applications in our daily
life
Let us discuss some of these applications

4. RATIO AND PROPORTIONSRATIO AND PROPORTIONS
A ratio expresses the magnitude of
quantities relative to each other
The quantities being compared in a
ratio might be physical quantities
such as speed or temperature, or
may simply refer to amounts of
particular objects

6. To create dishes with good flavor,
consistency, and texture, the various
ingredients must have a kind of relationship
to one another
Dilution in biology
In mathematics and the arts, two quantities
are in the golden ratio if the ratio of the
sum of the quantities to the larger quantity is
equal to the ratio of the larger quantity to the

7. The golden ratio is often denoted by the
Greek letter phi usually lower case (φ).
GOLDEN RATIO is used in:
Geometrical analysis
Architects, artists, book designers use
the golden ratio
Leonardo da Vinci’s illustrations of
polyhedra
 =1.6180339887φ

8. GEOMTRYGEOMTRY
The word geometry literally means "to
measure the Earth."
Geometry is the branch of math that is
concerned with studying area, distance,
volume, and other properties of shapes and
lines.

9. A = l * b in other words, "area equals
length times width." This formula is used
to determine the area of a rectangle or
square
A = (pi) x r2. This formula means "area
equals pi times the radius squared.”

10. SAVINGS AND CREDITSAVINGS AND CREDIT

11. There are two basic kinds of interest: simple
and compound interest.
With some maths smarts and an
understanding of simple and compound
interest, you can manage the way your money
grows .The formula for simple interest is;
I = Prt
Where,
I = interest
P = principal
r = interest rate (per year)
t = time (in years or fraction of a year)

12. Formula for calculating compound
interest: A=P(1+r/n)nt
Where, P = principal amount (initial
investment)
r = annual nominal interest rate (as a
decimal)
n = number of times the interest is
compounded per year
t = number of years
A = amount after time t

13. Exponential growthExponential growth
Exponential growth (including exponential
decay) occurs when the growth rate of a
mathematical function is proportional to the
function's current value.
Maths also help us in understanding
population growth, growth of
microorganisms
A family tree

14. Population grows in the same way that
money grows when it's left to compound
interest in a bank
A crucial difference between money and
population is that money can increase
without limits while population can't.

15. A quantity x depends exponentially on
time t if
x(t) = a. bt/T
where the constant a is the initial value of
x,
x(0)=a

16. CONCLUSIONCONCLUSION
Mathematics is the only language shared by
all human beings regardless of culture,
religion, or gender.
With this universal language, all of us, no
matter what our unit of exchange, are likely
to arrive at math results the same way
This math literacy is called numeracy, and it
is this shared language of numbers that
connects us with people across continents
and through time

17. With this language we can explain the
mysteries of the universe or the secrets of
DNA
 We can build computers and transfer
information across the globe.

18. SOCIAL APPLICATIONSSOCIAL APPLICATIONS
Math is not just for calculus majors. It's
for all of us. And it's not just about
pondering imaginary numbers or
calculating difficult equations. It's about
making better daily decisions and,
hopefully, leading richer, fuller lives.
