The add up case is not opposite to what is written in Holy Quran; while in the division of estate many cases are mentioned but it does not include all of them, because of that when some conditions appeared and Quran had not mentioned them, the condition is dealt with endeavour (great ingenuity). But even endeavour in this case should be confined to the shares that their quantities settled in Quran.. The source of the slander is not true; because it supposes that these cases that the experts and scholars endeavour to solve were the very same with the allotments mentioned in Qura , and this is not true! But they are rather new cases and after exploring them it became clear that dividing it according to the known fixed shares is not mathematically possible and because of this they did what is known as add up. And this is an endeavor concerned issue in non Quranic cases that are juristic reasoning depending on Quranic cases and inventing a new standard –based on inheritance division- so to have the shares match.. Quran is wrong if in it these shares stated particularly for the case of the husband and two sisters or the case of wife with parents and three daughters, and then objection is justified. But while the case itself is not stated in Quran, then objection is not right since it is an issue happened after Quran, and even not within the cases that are mentioned in Holy Quran. Allah the Almighty knows the best.
