  2. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    For example, one proof notes that if could be represented as a ratio of integers, then it would have in particular the fully reduced representation ⁠ a / b ⁠ where a and b are the smallest possible; but given that ⁠ a / b ⁠ equals so does ⁠ 2b − a / a − b ⁠ (since cross-multiplying this with ⁠ a / b ⁠ shows that they are equal).

  3. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Examples include ⁠ 1 / 2 ⁠, − ⁠ 8 / 5 ⁠, ⁠ −8 / 5 ⁠, and ⁠ 8 / −5 ⁠. The term was originally used to distinguish this type of fraction from the sexagesimal fraction used in astronomy. [10] Common fractions can be positive or negative, and they can be proper or improper (see below).

  4. Chart - Wikipedia

    en.wikipedia.org/wiki/Chart

    A radar chart or "spider chart" or "doi" is a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. A waterfall chart also known as a "Walk" chart, is a special type of floating-column chart. A tree map where the areas of the rectangles correspond to values. Other dimensions can be ...

    The form comes with two worksheets, one to calculate exemptions, and another to calculate the effects of other income (second job, spouse's job). The bottom number in each worksheet is used to fill out two if the lines in the main W4 form. The main form is filed with the employer, and the worksheets are discarded or held by the employee.

  7. Radar chart - Wikipedia

    en.wikipedia.org/wiki/Radar_chart

    A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative, but various heuristics, such as algorithms that plot data as the maximal ...

  8. Simple function - Wikipedia

    en.wikipedia.org/wiki/Simple_function

    In the mathematical field of real analysis, a simple function is a real (or complex)-valued function over a subset of the real line, similar to a step function.Simple functions are sufficiently "nice" that using them makes mathematical reasoning, theory, and proof easier.

  9. Karnaugh map - Wikipedia

    en.wikipedia.org/wiki/Karnaugh_map

    The POS expression gives a complement of the function (if F is the function so its complement will be F'). [10] Karnaugh maps can also be used to simplify logic expressions in software design. Boolean conditions, as used for example in conditional statements, can get very complicated, which makes the code difficult to read and to maintain. Once ...
