Rang in math

In mathematics, the term "rang" is not commonly used. It may be a misspelling of "range," which refers to the difference between the largest and smallest values in a set of numbers.

For example, if you have a set of numbers {2, 5, 8, 10, 12}, the range would be 12 (largest number) - 2 (smallest number) = 10.

If you meant something else by "rang," please provide more context so that I can assist you better.
