## Math From Scratch Delay

July 31, 2014 by W. Blaine Dowler math from scratch Bureau 42 Teaches

Unfortunately, “Math From Scratch” will be taking an unscheduled break. It will come back, I assure you; I enjoy making it far too much. I tried to go without volume breaks and shouldn’t have; things got suddenly much, much busier at work this month, and I discovered when writing the August entry that there are several assumptions and prerequisites that I missed in my original outline that require restructuring. I hope to have things back on track for October, and I apologize for the delay.
