It got its name undefined from the fact that it is impossible to divide by zero.
What does undefined mean in math examples.
The most famous example is that division by zero is undefined.
Recall that 6 2 equal 3 because 3 2 6 however it is impossible to do 5 0 because there exist no number you can multiply 0 by to get 5.
For example division by zero is undefined in the field of real numbers.
In algebra a function is said to be undefined at points not in its domain.

Undefined is a term used when a mathematical result has no meaning.
In our time we can say that 5 8 is undefined in the set of positive integers.
An expression in mathematics which does not have meaning and so which is not assigned an interpretation.
For example in the real number system is undefined for negative.
More precisely undefined values occur when an expression is evaluated for input values outside of its domain.
Ambiguous complex infinity directed infinity division by zero ill defined indeterminate well defined.
For instance during the time when the negative numbers were not yet invented the numerical expression 5 8 has no meaning.
For example in the equation ax by c the relation between x and y is indeterminate because you can t determine it without knowing the values of a b and c.
Think of it as the value where you end with more question marks at the end.
In arithmetic some arithmetic operations are called undefined.
Broadly speaking undefined means there is no possible value or there are infinite possible values while indeterminate means there is no value given the current information.
What does undefined mean.
