N-ary Number System Visual Learning Tool

"How do you convert binary numbers back to decimal?" "What are A and F in hexadecimal?" This is an N-ary number learning tool that lets you verify such questions by actually manipulating numbers.

It supports conversion from decimal to N-ary, from N-ary to decimal, and further conversion from N-ary to another M-ary number system. Since it handles bases 2 through 36, you can experience not only the commonly used binary, octal, decimal, and hexadecimal systems, but also larger bases using A through Z.

Rather than just displaying conversion results, you can also check the calculation process step-by-step, such as "reading remainders in order after division" and "multiplying each digit by the appropriate power of the base and adding them up." You can view the weight of each digit in card format, represent numbers as quantities using dots, check binary bit displays, and confirm the correspondence between binary and hexadecimal—making it easier to visually understand mechanisms that are difficult to grasp with numbers alone.

Additionally, it provides a list of usable digits and alphabets for each base, concrete examples of binary, octal, decimal, and hexadecimal, and practice problems.

This is a learning app designed to help you understand the mechanisms of N-ary number systems in an enjoyable way while resolving the question of "I got the answer, but why is it that way?"
