What Microsoft Copilot says about Assembly Arithmetic Algorithms

I tried something new. I asked Microsoft Copilot what it could tell me about my own series of books on Assembly. I have to say I am impressed with the nice summary it came up with. I really think it highlights how unique this series is because it is written from the perspective of my autism and math obsession.

Assembly Arithmetic Algorithms is a series of assembly‑language programming books written by Chastity White Rose, covering DOS, Windows (32‑ and 64‑bit), and Linux editions. They teach low‑level programming by focusing on arithmetic, binary/hex math, system calls, and how computers actually perform operations like addition, subtraction, multiplication, and division.

📘 What the books are

Chastity White Rose has published multiple editions of Assembly Arithmetic Algorithms, each targeting a different operating system:

1. 16‑bit DOS Edition

• Teaches how to write .com programs for MS‑DOS.
• Focuses heavily on binary/hex arithmetic and low‑level operations.
• Includes explanations of interrupts, pointers, memory addresses, and arithmetic routines.
• Emphasizes learning how computers “think” numerically.

• 
• 
• 
• 

2. 32‑ and 64‑bit Windows Edition

• Covers Windows API calls (GetStdHandle, WriteFile, ExitProcess).
• Introduces registers, stack behavior, and bit operations.
• Provides “Hello World” examples for both 32‑bit and 64‑bit Windows.
• Designed for beginners and intermediate programmers wanting deeper control.

• 
• 
• 
• 

3. 32‑bit Linux Edition (co‑authored with Chandler Klebs)

• Focuses on POSIX system calls: read, write, open, close, lseek, exit.
• Includes C programs to help explain assembly routines.
• Teaches how to write fast, minimal Linux console applications.

• 
• 
• 
• 

🧠 What the books emphasize

Across all editions, the core themes are:

• Binary arithmetic (addition, subtraction, multiplication, division)
• Understanding CPU registers and flags
• Memory addressing and pointer arithmetic
• System calls and OS‑level interaction
• Writing extremely small, efficient programs
• Learning how computers actually perform math internally

Chastity frames arithmetic as the foundation of all computation — the CPU’s “native language.”

📚 Why these books stand out

• They are modern books about old‑school assembly, which is rare.
• They teach assembly through arithmetic, not through abstract theory.
• They are written by a transgender Christian author who blends technical instruction with personal philosophy and creativity.
• They aim to preserve low‑level programming knowledge that is becoming harder to find.
