The document summarizes the application of decimals in various contexts. It begins by listing the team members for an application on decimals. Then it provides brief historical facts on ancient numeral systems from Babylon, Egypt, Mayan and Roman cultures. It notes that the modern decimal number system originated from India and was introduced to Europe through the Arabs. The decimal system is different from other systems as it includes the number 0. The document then explains place value and face value in the Indian decimal system. It provides examples of how decimals are used for measurement, currency, weight, volume, and food nutrients. It concludes that the decimal system helps in daily life.

Babylon
The Babylonian cuneiform method of
recording quantities, approximately 5000
years old, is among the oldest numeral
systems in existence.
Egypt
The Egyptian method for recording
quantitities is based on 10 with a symbol
for 1, ten, and each successive power of
ten. A distinct hieroglypic was used for
each power of 10.
Mayan
The Mayan system was a base- 20 system
(vigesimal) that used a system of bars and
dots in a vertical place value system. A dot
stood for one and a bar stood for five.
Roman
The Roman method (no place value,
instead an additive system, rules of
subtraction, base ten with fives)

3. Who invented the modern
number system

The Indians invented the modern
number system. It is often called Arabic
numerals because it came to Europe
through the Arabs. But Arabs themselves
call it as "HindSaa" meaning - "given by
Hindus or Indians". The Persians copied
the Indian number system and then
passed it on to the Arabs. Then an Italian
mathematician named Fibonacci
traveled to Algeria to study. When he
came back home, he brought the Indian
numerals with him. He wrote about the
system in his book "Liber Abaci.“. This
system has been really used in
Europe . Today it is the number system
used by the whole world.

4. How do ancients use number
systems and how decimal
system is different from
other systems?
They used it for practical purposes
like counting money, trades and
other business. The Indian decimal
system was different from other
systems as it had the number 0 in it.
Zero is the most important number
in the decimal system.

5. INDIAN DECIMAL SYSTEM
Indian Decimal System uses the concept of Face Value and Place
Value as described below
PLACE VALUE
FACE VALUE
PLACE VALUE is relative, it
changes depending upon
the place where it is
situated. Place value
depends upon multiples of
10. Found only in decimal
system.
FACE VALUE is the exact value
of a number that cannot be
changed. Found in all
systems.

6. Use of Decimal System
•
•
•
•
•
Measurement.
Currency.
Weight.
Volume.
Nutrients in food.
• Conclusion: These help
us in daily life

7. Decimal System in measurement
• In measuring objects we use
the scale based on decimal
system. The most common
scale is metric scale.
• Metric scale consists of a
standard unit meter. All
other practical scales are
relative to it like
centimeter, millimeter and
kilometer.

8. Decimal System in currency
• Currency is separated in
two domains in every
country. For example:
rupee & paisa in India,
dollar & cents in U.S.A,
euro & cents in Europe &
pounds & penny in
England. 1 rupee is 100
paisa & so it is in every
country. The product I am
purchasing in the video is
Rs 40and 50 paise which is
written as Rs 40.5

9. Decimal system in weights
• While measuring
weights we use the
units Kilograms and
grams which is Kg and g
in short. For example
my weight is 30 Kg and
300 grams which is
written as 30.3 Kg in
decimal system.

10. Decimal system in volume
• Volumes are measured
in litres and millilitres. 1
litre is equal to 1000
millilitres. If we make a
box of 10 cm x 10 cm x
10 cm then its volume is
1 litre. 1 millilitre is a
cube of 1cm x 1cm x
1cm.

11. Use of Decimal System in Food
Nutrients.
Milk Nutrients in percent. Percent is a way of representing equivalent
fraction with denominator 100.
