  2. Mathematical Operators (Unicode block) - Wikipedia

    en.wikipedia.org/wiki/Mathematical_Operators...

    Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.. Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (±), multiplication sign (×) and obelus (÷), due to them already appearing in the Latin-1 Supplement block ...

  3. Subtraction - Wikipedia

    en.wikipedia.org/wiki/Subtraction

    The minuend digits are m 3 = 7, m 2 = 0 and m 1 = 4. The subtrahend digits are s 3 = 5, s 2 = 1 and s 1 = 2. Beginning at the one's place, 4 is not less than 2 so the difference 2 is written down in the result's one's place. In the ten's place, 0 is less than 1, so the 0 is increased by 10, and the difference with 1, which is 9, is written down ...

    An expression like 1/2x is interpreted as 1/(2x) by TI-82, [3] as well as many modern Casio calculators [36] (configurable on some like the fx-9750GIII), but as (1/2)x by TI-83 and every other TI calculator released since 1996, [37] [3] as well as by all Hewlett-Packard calculators with algebraic notation.
