There is the star (✳), the dot (●), and the x, and sometimes, if it is a variable, it can just be, for example, 180y
The symbols on a calculator represent different mathematical operations. For example, the "+" symbol is used for addition, the "-" symbol for subtraction, the "x" symbol for multiplication, and the "/" symbol for division. Other symbols like "^" represent exponentiation, "√" for square root, and "π" for the mathematical constant pi. Understanding these symbols is crucial for performing accurate calculations on a calculator.

A mint mark is a letter or other symbol to indicate where a coin was minted.
The sign or abbreviation to represent an element is called an "atomic symbol", and there is a distinct one for each element. Every atomic symbol begins with a capital letter, which may constitute the entire symbol but is usually followed by a lower case letter.
In science, the symbol "m" can represent various quantities depending on the context. It is commonly used to denote mass, but it can also represent other variables such as slope, meters (in units of measurement), or molality (a concentration unit).
X is the symbol for multiplication, as in 2X2=4 X (or any other letter) is often used to represent an unknown quantity.
Usually represent a stream, river, or other body's of water.
The first or only letter of an element symbol must be capital; any other letter(s) must be lower case. (So far, there is never more than one other letter in the permanent symbol for any element, but the temporary names of some of the highest atomic weight elements often include two additional letters.)
The hazard symbol for methanol fuel is a flame symbol with a letter "F" inside it, indicating its flammable nature as a liquid. It may also include a skull and crossbones symbol to represent its toxic properties.
Such a symbol is called a "variable". It can be a letter, a group of letters (especially in computer programming), or a letter with a subscript (a lowered number, or some other letter - this is more common in math). The letters need not be from the Latin alphabet; Greek letters, or sometimes Hebrew letters, are also used.
x or any other variable
One explanation I was given was that when a letter was needed to represent current in formulas, C had already been used, and it was decided to use the next unused letter of the alphabet, which was I. However, I prefer the other explanation, which is that in the early days of investigations into electricity, what we now call current was called Intensity, hence the letter I. It should never be confused with Impedence, the symbol for which is Z.
The three letter symbol is given on the basis of its atomic no. whereas the other symbols are given for historical reasons or properties.
The sacrament truly bring about what they represent and the sign is a symbol of something
