## Math From Scratch Delay

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.
