Could you please explain the calculation of inheritances in detail, in the easiest possible way?

If the question is about the chapter of "Hisab" (calculation) in the science of inheritance, then what is meant is the تأصيل (establishing the root number) of fractional shares and their تصحيح (correction). تأصيل (establishing the root number) of issues means finding the smallest number from which the fraction of the issue or its fractions can be derived. تصحيح (correction) of issues is extracting the smallest number from which each heir receives their share without any fraction. The roots of issues are six: 2, 3, 4, 6, 8, 12, 24. And the jurists specializing in inheritance added two more roots in the chapter of the grandfather and siblings, which are 18 and 36. For further detail, one can refer to books on inheritance or study under a proficient scholar.
