About operators exercise

I found it too too long. Few suggestions to better focus on operators only:

• Provide in the original code the normalize() function and std::gcd stuff.
• Provide int the original code the constructors, public attributes, constructors, assign method, and externals functions such as multiply, add, compare (returning -1,0,1 ?), print.
• Ask to replace the functions with operators: =, +, *, <=>, <<
• Then ask to add, reusing previous ones: !=, +=, *=.
• Show that with <=> implemented, then <, <=, >, >= are automatically infered ?
• Optionally, make all the assignments returning *this, like in operator<<, and explain this permit chaining.
• Optionally, make them move the operators as inline friend functions, and make attributes private.
• Optionnaly, discuss the pros and cons of making the unary constructor explicit.

Start by locating the operators exercise and reviewing its current instructions, especially the existing normalize() and std::gcd material. Compare the exercise with the proposed operator-focused sequence, including constructors, arithmetic and comparison operators, compound assignments, chaining, and optional design discussions; done means the exercise is shorter and its operator scope is clear.
