Abscissa and ordinate is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative; after: positive). Usually these are the horizontal and vertical coordinates of a point in a two-dimensional rectangular Cartesian coordinate system. The terms can also refer to the horizontal and vertical axes respectively (typically "x"-axis and "y"–axis) of a two-dimensional graph. An ordered pair consists of two terms—the abscissa (horizontal, usually "x") and the ordinate (vertical, usually "y")—which define the location of a point in two-dimensional rectangular space. Though the word "abscissa"
Bit-paired keyboard but bit-paired keyboards have (rows 10, 11, and 13) instead of and are missing the key, as these are shifted values of digits. This is the complete set of symbols on the Model 33; it is notably missing though these are present on other bit-paired keyboards. On both bit-paired and typewriter-paired keyboards, are paired (rows 11, 12, and 13), but on bit-paired keyboards are paired and is an unpaired key, while on typewriter-paired keyboards and are shifted digits, while are paired and is paired with . In the US, bit-paired keyboards continued to be used into the 1970s, including on
