I’m 70% done with 6th grade math on Khan Academy, but subtraction still drives me crazy! My dad taught me a new subtraction algorithm, which was apparently the most common algorithm taught between 1700 and 1900 – but more on that later, once I figure out how to get access to the academic journals. ;)

- Video production time: 1 hour (estimated)
- Script writing/preparation: none
- Filming/setup: 15 minutes (estimated)
- Video editing: 31 min
- Publishing: 15 min
- Math study time: 2 hours
- Practice problems: 2 hours
