Study Notes

Nature of Mathematics

  • Language of mathematics is a system of conventional spoken, manual (signed), or written symbols that express human thought.
  • Mathematics language has its own set of symbols, including English alphabet, numerals, Greek letters, grouping symbols, and special symbols.

Mathematics Language vs. English Language

  • Difficulties arise from different meanings or uses of words in math and English, such as "and" equivalent to plus and "is" having different meanings.
  • Numbers have different uses in math: cardinal (counting), ordinal (telling positions), and nominal (identifying).

Translation: English to Math Language

  • Example translations: y = x, x = y, input-output functions, and function notation.

Functions

  • A function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range).
  • Vertical Line Test: if a vertical line intersects the graph of a relation at more than one point, then the relation is not a function.
  • Examples of functions and non-functions are provided.

Elementary Logic

  • Logic serves as a set of rules governing the structure and presentation of mathematical proofs.
  • A proposition is a statement that is either true or false, and can be expressed in symbols P, Q, R, or p, q, r.

Sets

  • A set in mathematics is a collection of well-defined and distinct objects, considered as an object in its own right.
  • Equivalent sets have the same cardinal number, while equal sets have identical elements.

KeyWords to Remember

  • equals (=) is, are, was, were, will be, gives, yields, sold for, cost
