The symbol used to denote inequation (when items are not equal) is a slashed equal sign ≠ (U+2260). In LaTeX , this is done with the " eq" command. Most programming languages, limiting themselves to the 7-bit ASCII character set and typeable characters , use ~= , != , /= , or <> to represent their Boolean inequality operator .
Encoding. The triple bar character in Unicode is code point U+2261 ≡ IDENTICAL TO ( ≡, ≡ ). [1] The closely related code point U+2262 ≢ NOT IDENTICAL TO ( ≢, ≢) is the same symbol with a slash through it, indicating the negation of its mathematical meaning. [1]
A ⊂ B {\displaystyle A\subset B} may mean that A is a proper subset of B, that is the two sets are different, and every element of A belongs to B; in formula, A ≠ B ∧ ∀ x , x ∈ A ⇒ x ∈ B {\displaystyle A eq B\land \forall {}x,\,x\in A\Rightarrow x\in B} . ⊆. A ⊆ B {\displaystyle A\subseteq B}

Tally marks, also called hash marks, are a form of numeral used for counting. They can be thought of as a unary numeral system. They are most useful in counting or tallying ongoing results, such as the score in a game or sport, as no intermediate results need to be erased or discarded.
The slash is the oblique slanting line punctuation mark /. It is also known as a stroke, a solidus, a forward slash and several other historical or technical names. Once used to mark periods and commas, the slash is now used to represent division and fractions, exclusive 'or' and inclusive 'or', and as a date separator .
The number sign was assigned code 35 (hex 0x23) in ASCII where it was inherited by many character sets. In EBCDIC it is often at 0x7B or 0xEC. Unicode characters with "number sign" in their names: U+0023 # NUMBER SIGN Other attested names in Unicode are: POUND SIGN, HASH, CROSSHATCH, OCTOTHORPE. U+0600 ARABIC NUMBER SIGN; U+0BFA ௺ TAMIL ...
After that, mathematicians simplified Pierre's symbol to "less than (greater than) or equal to with one horizontal bar" (≤), or "less than (greater than) or slanted equal to" (⩽). The relation not greater than can also be represented by the symbol for "greater than" bisected by a slash, "not".
