PraveenMohan13/numbers ? reverse-engineered prompt

Build me a simple beginner friendly numbers toolkit from this repo. It looks like a collection of small programs about number operations and checks, so I want it cleaned up into one consistent project that’s easy to run and understand.

The app should let someone enter a number, or in a few cases a range or two binary values, and then use the features already suggested here, like prime number checks, primes in a range, palindrome, Armstrong, automorphic, factorial, Fibonacci series, power of a number, reverse a number, counting digits, summing digits, reducing to a single digit, sum of prime digits, binary addition, binary to decimal, half reverse, and finding a max product if that’s already part of the existing logic.

Please make the experience simple and clear, either as a small menu based program or another straightforward interface if that fits better. Keep naming consistent, handle invalid input nicely, and add a short readme so a beginner knows what each feature does and how to run it. Look up current docs online if you need to.
