The reciprocal function: y = 1/x.For every x except 0, y represents its multiplicative inverse. The graph forms a rectangular hyperbola.. In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.
The multiplicative identity is 1; anything multiplied by 1 is itself. This feature of 1 is known as the identity property : [ 27 ] [ 28 ] x ⋅ 1 = x . {\displaystyle x\cdot 1=x.}
In algebraic notation, widely used in mathematics, a multiplication symbol is usually omitted wherever it would not cause confusion: "a multiplied by b" can be written as ab or a b. [ 1 ] Other symbols can also be used to denote multiplication, often to reduce confusion between the multiplication sign × and the common variable x .

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 (+) is the product of and (+) (indicating that the two factors should be multiplied together).
Approximately 38.4 million Americans had been diagnosed with diabetes as of 2021 — but about three times that many are in danger of developing the disease, even if they don’t know it. Nearly ...
Multiplying a number by −1 is equivalent to changing the sign of the number – that is, for any x we have (−1) ⋅ x = −x.This can be proved using the distributive law and the axiom that 1 is the multiplicative identity:
One of two remaining co-defendants in Georgia's longest-running criminal trial was stabbed in jail, his lawyer said Monday morning, as jurors resumed deliberations in the sprawling racketeering ...
