Thank you for the lesson! Your videos are always a great help to me, just a note, on practice problem b there's actually five zeros after the decimal before the four. So the ten has an exponent of -6 instead, which becomes -2 when you add the four. Then when you add the two to the six you get 1 x 10^8 as your final answer instead of 1 X 10^7. Just a little helper to anyone else who also uses these videos for homeschool and was confused as to why the answer book was a bit different. It took me a bit to realize it myself.
