Study Notes
Basic Mathematical Symbols
- Symbols represent mathematical operations and relationships
- Equals sign (=) indicates equality, e.g., 5 = 2 + 3
- Not equal sign (≠) represents inequality, e.g., 5 ≠ 4
- Approximately equal sign (≈) denotes an approximation, e.g., sin(0.01) ≈ 0.01
- Greater than (>), less than (<), greater than or equal to (≥), and less than or equal to (≤) are inequality symbols
- Parentheses () and brackets [] specify order of operations
- Plus sign (+), minus sign (-), plus-minus (±), and minus-plus (∓) represent addition, subtraction, and combinations thereof
- Times sign (×) and multiplication dot (⋅) denote multiplication
- Division sign (÷), division slash (/), and horizontal line (=) are used for division operations
- Period (.) denotes a decimal point
- Power (exponent) is represented by a superscript
- Square root (√), cube root (∛), and nth root (√) denote corresponding operations
- Factorial (!), open interval, and closed interval are used in mathematical expressions
Plural
- Plural nouns represent more than one person, place, thing, or concept
- Regular plural forms are typically created by adding "-s" to the singular noun, e.g., book → books
- Irregular plural nouns have unique plural forms, e.g., child → children, man → men, woman → women
- Nouns ending in "s," "ss," "sh," "ch," "x," or "z" often take "-es" to form their plural, e.g., bus → buses, quiz → quizzes
- Nouns ending in "y" preceded by a consonant change "y" to "ies," e.g., theory → theories
- Some nouns ending in "f" or "fe" change to "ves" in the plural, e.g., knife → knives
- Some nouns with Latin or Greek origins have unique plural forms, e.g., alumnus → alumni, thesis → theses, phenomenon → phenomena
Articles
- Articles (a/an, the) are used with nouns to specify if the noun is specific or general
- "A" or "an" are used before singular countable nouns for the first mention or for general reference, e.g., a book, an apple. "A" is used before words starting with consonants, and "an" is used before words starting with vowels
- "The" is used before nouns to indicate a specific or previously mentioned noun, e.g., the book, the house
- Articles are not used with plural nouns or uncountable nouns in certain situations when making general statements, e.g., Gold, iron and copper are metals.
