2. Math or Coding Books: Consider gifting your husband some books related to mathematics or coding. There are numerous titles available that explore different branches of mathematics, such as calculus, number theory, or cryptography. Alternatively, you could choose a book on programming languages or coding fundamentals to pique his interest.

3. Enroll in an Online Course: If your husband is interested in coding or wants to learn more about mathematics, consider enrolling him in an online course. Websites like Udemy or Coursera offer a wide range of courses, including programming languages, data analysis, or even advanced mathematics topics.

4. Unique Calculator: Since your husband seems to enjoy numbers, a unique or personalized calculator could be an interesting gift. Look for calculators that have additional functions or special designs, such as a retro-style calculator, a scientific calculator with advanced features, or even a programmable calculator.

5. Math Art or Decor: Consider getting your husband math-themed artwork or decorative items for his workspace or home. There are various posters, prints, and sculptures available that depict mathematical concepts, formulas, or patterns. This could be a great way to incorporate his interest into his everyday environment.

6. Personalized Gift: You can always opt for a personalized gift that incorporates his interest in math or coding. For example, you could get a custom-made piece of jewelry, such as a bracelet or pendant, with a mathematical equation or code engraved on it. Another option is to have a custom-designed t-shirt or mug featuring a math-related joke or phrase.

Remember, it's important to consider your husband's individual preferences and interests to find a gift that truly resonates with him. While the specific interest mentioned may not have any readily available merchandise, exploring related areas can still lead to a thoughtful and meaningful gift.
