    • Discuss language, symbols, and conventions in mathematics.
    • Explain the nature of mathematics as a form of language.
    • Perform operations on mathematical expressions correctly.
    • Acknowledge the usefulness of mathematics as a language.

    Class Policies and Requirements

    • Problem sets must be submitted on time; late submissions incur point deductions.
    • Cheating results in an automatic failing grade.
    • Proper decorum is required in all communications, including online interactions.
    • Use black or blue pens for problem sets.

    Grading System

    • Assignments/Exercises: 20%
    • Quizzes: 20%
    • Problem Sets: 20%
    • Term Examinations: 40%
    • Total: 100%

    Mathematical Language and Symbols

    • Mathematical language is characterized by:
      • Precision: Makes fine distinctions clear.
      • Conciseness: Expresses ideas briefly.
      • Power: Conveys complex thoughts with ease.

    Learning and Practice

    • Learning mathematical language requires effort similar to learning a foreign language.
    • Extensive practice enhances abilities to read, write, speak, and understand mathematics.

    Classification of Mathematical Components

    • Nouns in Mathematics: Represent mathematical objects of interest.
    • Sentences in Mathematics: State complete mathematical thoughts.

    • Understanding the difference between nouns and sentences helps avoid common syntax errors.
    • Example of syntax error: Inappropriately equating expressions or misusing the equal sign.

    Comparison of English and Mathematics

    • English Nouns and Sentences: Nouns name entities; sentences express complete thoughts.
    • Mathematical Expressions and Sentences:
      • Expressions: Analogous to nouns; represent mathematical objects.

    Unit 2: Mathematical Language and Symbols

    Characteristics of Mathematical Language

    • Precision: Mathematics allows for fine distinctions in meaning.
    • Conciseness: Mathematical expressions convey ideas succinctly.
    • Powerful Expression: Complex thoughts can be articulated with relative ease.

    Mathematical Language Structure

    • Vocabulary and Rules: Mathematical language consists of "nouns" (expressions) and "sentences" (statements).
    • Syntax Awareness: Understanding the classification helps to avoid syntax errors, such as incorrectly using equal signs.

    Expressions vs. Sentences

    • Analogous to English:
      • Nouns in English correspond to Expressions in mathematics, denoting objects or numbers.
      • Sentences in both languages state complete thoughts.

    Examples of Expressions and Sentences

    • Expressions: Represented by mathematical objects like numbers (e.g., 5, 2 + 3).
    • Sentences: Are statements that provide complete thoughts (e.g., 3 + 4 = 7).

    Importance of Names in Mathematics

    • Numbers can be represented in multiple ways, analogous to synonyms in English.
    • Example Synonyms: For the number “three”, different expressions include:
      • Using a plus sign: 1 + 2
      • Using a minus sign: 5 - 2
      • Using a division sign: 6 ÷ 2

    Truth Values of Sentences

    • Sentences can be categorized as true or false based on their mathematical validity.
    • Example Truth Values:
      • Always true: (7 - 3 = 4)
      • Always false: (7 - 3 = 5)
      • Sometimes true: (x + 10 = 11) (depends on the value of x)

    Conventions in Mathematical Language

    • Conventions in mathematics aid in distinguishing expression types (e.g., capitalization in English).
    • Understanding conventions helps clarify expressions and their meanings within mathematical contexts.

    Determining Expressions and Sentences

    • To identify if an item is an expression or a sentence:
      • Assess if it expresses a complete thought (is it true or false?).
      • Example: "1 + 2" does not state a complete thought, whereas "1 + 2 = 3" does.

    Assignments and Applications

    • Complete exercises to reinforce concepts by identifying nouns and sentences in both mathematics and English.
    • Explore truth values and the role of connectives in mathematical sentences.
