A symbol or word in an expression is called a "term." In mathematical expressions, terms can include numbers, variables, or constants that are combined through operations such as addition, subtraction, multiplication, or division. Each term contributes to the overall value of the expression. In broader contexts, terms can also refer to specific words or phrases used in a particular field or discipline.
I assume that the expression is 4/5 (thanks to the rubbish browser, the division symbol is not visible). In that case, 5 is the denominator (or divisor).
The point where the radical emerges is called the "radical sign" or "radical symbol," typically represented by the symbol √. This sign indicates the extraction of a root, most commonly the square root, of the number or expression that follows it. For example, in the expression √x, the radical sign signifies the square root of x.
The symbol 'π' is the Greek letter 'p' which is called "pi", like our 'p' is called 'pee'.
A power or exponent.
In an expression p4 is called a term.
algebraic expression
it is called a variable
Those are the "terms" of the expression.
A new invented word or expression is called a Neologism.
The a in circle symbol is the symbol for the word At. Example: soanso@(at)something.ca
is one symbol already an expression in math
& is called the ampersand.
The symbol representing the word "and" is called an ampersand (&).
I assume that the expression is 4/5 (thanks to the rubbish browser, the division symbol is not visible). In that case, 5 is the denominator (or divisor).
The real name of the symbol "&" is an ampersand. It is a logogram representing the word "and."
a variable expression in math is a symbol that is in a sentence
The point where the radical emerges is called the "radical sign" or "radical symbol," typically represented by the symbol √.
