研究方向
Start by reading #24 and its dependency #58, then locate the existing games and shared timed-practice lifecycle. Define the digit and precedence rules before implementing the generator and answer validation; the issue names no files or tests to start from. Done means the specified validation and generator tests pass, a browser test completes, corrects and restarts a round, and the game remains separate from Digit Recall.

描述
Part of #24. Depends on #58.
Student problem
Students need practice completing arithmetic expressions under digit-use constraints, with feedback that explains valid reasoning.
Scope
- Present an expression with missing operands and a target, initially forms such as
a × b + c = target. - Let students choose distinct digits from 1 to 9. Clearly state available digits, reuse restrictions and operator precedence.
- Generate solvable puzzles and accept any assignment that satisfies the expression and constraints, including alternatives to the generated solution.
- Increase difficulty through documented expression templates; keep operand selection and undo usable with keyboard/touch.
- Show a worked solution after submission in learning mode; timed practice uses the shared lifecycle.
- Keep free guest practice. Additional quick-calculation templates can follow once the core rules are reliable.
Done when
- Tests cover valid alternate answers, duplicate/out-of-range digits, incomplete input, precedence, impossible generated targets and difficulty bounds.
- Generators prove at least one legal answer exists.
- A browser test completes a round, corrects an operand and restarts.
Keep this separate from the existing Digit Recall memory exercise.
