how does multiplication and division undo each other
Two operations are said to undo each other if each operation is the inverse (NOT reciprocal) of the other. Often the domain and range of the operations will need to be restricted so that the inverse exists. Some examples: Addition and subtraction. Multiplication and division. Sine of an angle and arcsine of a ratio (similarly the other trig ratios). Square and square root. Exponentiation and logarithm. Thus 3-squared is 9 and the [principal] square root of 9 is 3. If the range of the square root function is not restricted to non-negative roots, then the square root of 9 could also be -3.
Such operations are said to be inverse relations. Examples include: * Addition versus subtraction * Multiplication versus division * Raising to a power vs. taking a root (if you solve for the base) * Raising to a power vs. taking a logarithm (if you solve for the exponent)
you multiply it by its reciprical or you multiply it by it flipped around which eaquals 1.
Inverse functions are two functions that "undo" each other. Formally stated, f(x) and g(x) are inverses if f(g(x)) = x. Multiplication and division are examples of two functions that are inverses of each other.
Two operations that undo each other are called inverse operations. Examples are addition and subtraction, or multiplication and division.
Inverse operations, or reciprocals.
Operation, and inverse operation
the Inverse Operation. This answer is relative to math, and operations.
Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Inverse operations, or opposite operations, undo one another. Subtraction undoes addition (and vice versa), and division undoes multiplication (and vice versa).
