The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date. The table can also be ordered alphabetically by clicking on the relevant header title.
Sometimes, multiplication symbols are replaced with either a dot or center-dot, so that x × y is written as either x. y or x · y . Plain text , programming languages , and calculators also use a single asterisk to represent the multiplication symbol, [ 6 ] and it must be explicitly used; for example, 3 x is written as 3 * x .
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
In some programming languages, concatenation of strings is written "a" + "b", and results in "ab". In most programming languages, subtraction and negation are indicated with the ASCII hyphen-minus character, -. In APL a raised minus sign (here written using U+00AF ¯ MACRON) is used to denote a negative number, as in ¯3.
In mathematics, a product is the result of multiplication, or an expression that identifies objects (numbers or variables) to be multiplied, called factors. For example, 21 is the product of 3 and 7 (the result of multiplication), and x ⋅ ( 2 + x ) {\displaystyle x\cdot (2+x)} is the product of x {\displaystyle x} and ( 2 + x ) {\displaystyle ...
The symbols for elementary-level math operations. From top-left going clockwise: addition, division, multiplication, and subtraction. Elementary arithmetic is a branch of mathematics involving addition, subtraction, multiplication, and division.
Investors this year have grown increasingly confident the US economy will achieve a "soft landing.". But the election of Donald Trump as the nation's next president has complicated the outlook ...
A term is a constant or the product of a constant and one or more variables. Some examples include ,,, The constant of the product is called the coefficient. Terms that are either constants or have the same variables raised to the same powers are called like terms. If there are like terms in an expression, one can simplify the expression by ...
