1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral.

In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions.

2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number.

Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.

4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures.

A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from generic or store brands.

The practice of branding—in the original literal sense of marking by burning—is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding and branded slaves as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a product or company, so that "brand" now suggests the values and promises that a consumer may perceive and buy into. Over time, the practice of branding objects extended to a broader range of packaging and goods offered for sale including oil, wine, cosmetics, and fish sauce and, in the 21st century, extends even further into services (such as legal, financial and medical), political parties and people's stage names.

In the modern era, the concept of branding has expanded to include deployment by a manager of the marketing and communication techniques and tools that help to distinguish a company or products from competitors, aiming to create a lasting impression in the minds of customers. The key components that form a brand's toolbox include a brand's identity, personality, product design, brand communication (such as by logos and trademarks), brand awareness, brand loyalty, and various branding (brand management) strategies. Many companies believe that there is often little to differentiate between several types of products in the 21st century, hence branding is among a few remaining forms of product differentiation.

Brand equity is the measurable totality of a brand's worth and is validated by observing the effectiveness of these branding components. When a customer is familiar with a brand or favors it incomparably over its competitors, a corporation has reached a high level of brand equity. Brand owners manage their brands carefully to create shareholder value. Brand valuation is a management technique that ascribes a monetary value to a brand.

Drywall (also called plasterboard, dry lining, wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, glass wool, or a combination of these materials); plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption.

In the mid-20th century, drywall construction became prevalent in North America as a time- and labor-saving alternative to lath and plaster.
