This week at first I didn’t fully understand lesson 1.5 until we learned 1.6. I didn’t understand how to put it into a form of an answer after the prime factorization step. I also had a lot of trouble with understanding the fractions.
After learning the next lesson it quickly became clear to me and started to become extremely easy, I even started to do the math in my head and was able to get the answer without writing it down in steps. Now all it is, is repetition.
