Final answer:
0=0 is an example of an identity in mathematics. An identity is an equation that is true for all values of the variable.
Step-by-step explanation:
0=0 is an example of an identity in mathematics. An identity is an equation that is true for all values of the variable. In this case, no matter what value we substitute in for the variable, both sides of the equation will always be equal to each other.
For example, if we substitute 5 for the variable, we get:
5 = 5
And if we substitute -2 for the variable, we get:
-2 = -2
In both cases, the equation is true.
