There are indeed various number systems used around the world, each with its own unique set of numerals. Here, I will describe three number systems other than the Hindu-Arabic system and discuss three reasons why the Hindu-Arabic numeral system has been widely preferred.
1. Roman Numerals:
The Roman numeral system originated in ancient Rome and is still used today in certain contexts. It employs a combination of letters to represent numbers. The basic symbols in the Roman numeral system are I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000). This system is primarily used in areas such as clock faces, book chapters, and decorative purposes. However, it is not as efficient for complex mathematical calculations due to its additive nature and lack of a zero symbol.
2. Mayan Numerals:
The Mayan civilization developed its own unique numeral system, which was vigesimal (base-20). The Mayan numerals utilized a combination of dots and bars, with a dot representing one and a bar representing five. The system was additive, similar to the Roman numerals, and lacked a symbol for zero. Mayan numerals were primarily used for record-keeping, calendrical calculations, and measuring time.
3. Chinese Numerals:
Chinese numerals, also known as Suzhou numerals, have a long history in China. They are derived from ancient Chinese counting rods and are still used in some contexts, particularly in financial transactions and traditional settings. The Chinese numeral system is based on decimal principles, with symbols for one through nine and additional characters for multiples of ten. It is notable for its simplicity and ease of use, but it lacks positional notation, making it less suitable for advanced mathematical calculations.
Now, let's discuss three reasons why the Hindu-Arabic numeral system has been preferred:
1. Positional Notation:
The Hindu-Arabic numeral system is based on a decimal system with positional notation. This means that the value of a digit depends on its position within a number, allowing for the representation of numbers of any magnitude. Positional notation makes mathematical operations much simpler and more efficient, enabling complex calculations to be performed accurately and swiftly. This contributed to the widespread adoption of the Hindu-Arabic system for advanced mathematics and scientific endeavors.
2. Use of Zero:
The Hindu-Arabic system introduced the concept of zero as a placeholder, which revolutionized mathematical notation. The inclusion of zero as a numeral allowed for the representation of empty places in positional notation, facilitating computations involving large numbers and fractions. The concept of zero was a significant mathematical development that had a profound impact on various fields, including algebra, calculus, and computer science.
3. Versatility and Adaptability:
The Hindu-Arabic numeral system is highly versatile and adaptable to different cultural, linguistic, and mathematical contexts. It can be easily combined with other numeral systems, such as the Roman numerals or Chinese numerals, to represent numbers in various ways. Additionally, the Hindu-Arabic numerals can be readily understood and used by people from different backgrounds and languages, making it a universal system for numerical communication and calculation.
In summary, while there are several number systems in the world, the Hindu-Arabic numeral system has emerged as the preferred choice for various reasons. Its positional notation, inclusion of zero, and versatility have made it the foundation of modern mathematics, facilitating complex calculations and providing a universal language of numbers.

According to Adam Smith, self-interest and competition act as an invisible hand, guiding guiding firms in a market-based economy.
How does self-interest and competition guide firms in a market-based economy?According to Adam Smith often regarded as the father of modern economics, self-interest and competition play a crucial role in guiding firms in a market-based economy.
Smith's concept of the "invisible hand" suggests that individuals pursuing their own self-interests in the pursuit of profit inadvertently contribute to the overall welfare of society. In a competitive market, businesses strive to maximize their own profits by offering desirable goods or services at competitive prices.

Give TWO reasons why pig
cannot be fed rough
Answer:
There are two main reasons why pigs cannot be fed rough or coarse feed:
1. Digestive System: Pigs have a relatively simple and monogastric (single-chambered) digestive system similar to humans. Their digestive tract is not designed to efficiently break down and extract nutrients from rough or fibrous materials. Pigs lack a rumen, which is present in ruminant animals like cows and helps them digest roughage effectively. Pigs have a shorter digestive tract optimized for digesting easily digestible and concentrated feeds.
2. Nutrient Requirements: Pigs have specific nutrient requirements for optimal growth, reproduction, and overall health. Rough or coarse feeds typically have lower nutrient density and may lack the essential nutrients required by pigs. Pigs need a balanced diet that provides the right amounts of protein, carbohydrates, fats, vitamins, and minerals. Feeding them rough feed alone may not meet their nutritional needs, leading to deficiencies and health issues.
To ensure proper nutrition and optimal growth, pigs require feeds that are formulated specifically for their dietary needs, typically consisting of grains, protein sources, and essential supplements. These formulated feeds are processed and balanced to provide the necessary nutrients in a digestible form for pigs.

PVT 1. Write a summary of types of industry and history of industrial revolution.
There are three main types of industry: primary, secondary, and tertiary. Primary industries involve the extraction of raw materials from the earth, such as mining, agriculture, and fishing. Secondary industries involve the processing of raw materials into finished products, such as manufacturing and construction. Tertiary industries involve the provision of services, such as healthcare, education, and hospitality.
The Industrial Revolution was a period of significant changes in the way goods were produced, beginning in the late 18th century in Britain and spreading to other parts of the world. The Industrial Revolution was characterized by the transition from hand production methods to machine-based manufacturing, which led to significant improvements in productivity and efficiency. The first phase of the Industrial Revolution focused on the development of textile manufacturing, while the second phase focused on the development of iron and steel production, transportation, and communication technologies. The Industrial Revolution had a profound impact on society, transforming the way people lived and worked, and paving the way for modern industrial economies.
