6. Truth table - Wikipedia

   en.wikipedia.org/wiki/Truth_table

   A truth table is a structured representation that presents all possible combinations of truth values for the input variables of a Boolean function and their corresponding output values. A function f from A to F is a special relation, a subset of A×F, which simply means that f can be listed as a list of input-output pairs. Clearly, for the ...

7. Mathematical markup language - Wikipedia

   en.wikipedia.org/wiki/Mathematical_markup_language

   A mathematical markup language is a computer notation for representing mathematical formulae, based on mathematical notation.Specialized markup languages are necessary because computers normally deal with linear text and more limited character sets (although increasing support for Unicode is obsoleting very simple uses).

8. Function (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Function_(mathematics)

   A bar chart can represent a function whose domain is a finite set, the natural numbers, or the integers. In this case, an element x of the domain is represented by an interval of the x -axis, and the corresponding value of the function, f ( x ) , is represented by a rectangle whose base is the interval corresponding to x and whose height is f ...
