This question already has an answer here:
It's common knowledge that Moshe received the Torah in Har Sinai. He wrote the Pentateuch directly dictated from Hashem there and brought it down. But we also learn that he came down with the Ten Commandments in the Luchot HaBrit (Stone Tablets) and that he broke them the first time when he saw the golden calf.
Did Moshe Rabbeinu came down the first time with the Pentateuch AND the Stone Tablets (which were broken) and a second time with just the Stone Tablets? How was the order and how could he carry all of this?
Side Note: I know the Torah Moshe brought down wasn't the complete Torah we read today; Yehoshua continued and finished it. The question marked as a duplicate does not answer my questions.
