Iris raised her hand again. "Well, Professor, when I was reading my text book, I read somewhere that everything - the life number, the destiny number etc... get put together to determine your overall path thing. so your over all Arithmancy profile would differ from that of your parents'." she said, cursing herself for forgetting what it was called - after all she was only a first year, surely it wasn't that bad to not completely remember everything, she hoped it still made sense though, "Also, like Satine just said, we have middle names, which are chosen by our parents because they thought it suited us, so if we included those when calculating our destiny number, then we would end up with a different number to our parents or grandparents." she added, hoping dearly that her answer was some what correct.
