AltGr+X → ź; AltGr+Z → ż (Because there are two types of "z with diacritic" (ź and ż), AltGr+X is a special case.) At the time of the Fall of communism and opening of commercial import channels this practice was so widespread that it was adopted as the de facto standard. Nowadays nearly all PCs in Poland have standard US keyboards and ...
In algebra, it is a notation to resolve ambiguity (for instance, "b times 2" may be written as b⋅2, to avoid being confused with a value called b 2). This notation is used wherever multiplication should be written explicitly, such as in " ab = a ⋅2 for b = 2 "; this usage is also seen in English-language texts.
Use of the letter x for an independent variable or unknown value. See History of algebra: The symbol x. 1637 [2] René Descartes (La Géométrie) √ ̅ .
2. Equivalence class: given an equivalence relation, [] often denotes the equivalence class of the element x. 3. Integral part: if x is a real number, [] often denotes the integral part or truncation of x, that is, the integer obtained by removing all digits after the decimal mark.
Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles.
Hex input of Unicode must be enabled. In Mac OS 8.5 and later, one can choose the Unicode Hex Input keyboard layout; in OS X (10.10) Yosemite, this can be added in Keyboard → Input Sources. Holding down ⌥ Option, one types the four-digit hexadecimal Unicode code point and the equivalent character appears; one can then release the ⌥ Option ...
ThinkLight was a keyboard light present on many older ThinkPad families of notebook computers. The series was originally designed by IBM, and then developed and produced by Lenovo since 2005. The ThinkLight has been replaced by a backlight keyboard on later generations of ThinkPads, and Lenovo has discontinued the ThinkLight in 2013. [1]
Mathcad calls this standard math notation. [32] Maple has a Math Equation Editor , [ 33 ] but does not have a special name for this input method. Texas Instruments calls it MathPrint, [ 34 ] incorporating it in its high-end calculators, such as the TI-Nspire series , and in 2011 added the feature to its TI-84 series with the 2.55 OS update.
