### Subject:Writing

Question:

What is the best way to create a well thought out written project?

Inactive
Maria F.

In my opinion, some of my best work has come from having a clear cut end goal in mind. This has come from writing the title of the project first. A title allows the reader to get the idea of your writing project before ever reading it. It is descriptive and serves as the first introduction of the piece, declaring the project as a whole. Some are concerned with writing a title before writing the piece because they do not want to impart bias. However, you are not responsible for the title you write originally. It only serves as a jumping off point, a guide for your piece.

### Subject:Basic Math

Question:

Describe the two ways to solve this problem, then discuss which you deem the most appropriate approach. 8 ÷ 2(2+2) = ?

1. Following PEMDAS linearly, first solve the parenthetical (2 + 2 = 4). Then, solve the multiplication and division in the order they are presented. (8 ÷ 2 = 4, then 4 x 4 = 16). The answer is 16 using this method. 2. Use the ÷ symbol as an indicator for a fraction. Therefore, linearly, the equation reads 8 / (2 (2+2)) = ? Then use PEMDAS starting with the parenthetical (2 + 2 = 4), then solve the denominator (2 x 4 = 8), then solve the fraction (8 / 8 = 1). Both methods are valid and highlight the issue of using the ÷ symbol past basic math. According to PEMDAS, multiplication and division are at the same level in the hierarchy, meaning they must be performed in order as presented. However, the ÷ symbol technically denotes the difference between the numerator (top) and the denominator (bottom) of a fraction. If the question were written in proper mathematical format given that assumption, then the denominator should have been within a parentheses (e.g. 8 ÷ (2 (2 + 2)) ). Therefore, according to PEMDAS, each "side" of the equation must be solved first before solving the division problem, or the equivalent of the second approach. Therefore, both are valid answers as written, but the ÷ symbol lacks the context necessary to acquire the desired result.

Question:

Describe the use and necessity of the four subfields of anthropology.

Linguistic anthropology aims to describe the use and structure of language, human interaction, as well as how language influences the perception and reflects the perspective of the individuals and communities in which it's used. Cultural anthropology investigates the structure of human societies and families in order to understand both how the culture came to be and how the culture ever influences the people who participate in it. Biological anthropology concerns everything that makes a human physically human, from the color of their hair to the shape of their bones to the blood and hormones under the surface. It also investigates Homo sapiens' place in the world from an evolutionary perspective, sometimes focusing on other primates and extant species. Archaeology combines the investigations of all the previous subfields, but attempts to investigate them without the actual presence of human material. Using what is left behind, both intentionally and not, archaeologists attempt to understand human past. All subfields are necessary in their own right and need the others to bolster their individual work. Linguistic studies directly inform culture studies, and vice versa. Culture can be embodied into a human, influencing variation within the biology of the human species. Understanding human past is necessary to understand the linguistics, culture, and biology of human present and future.
