### The 7 Critical Deduction Traps:
1. Omitting '±' symbol when taking square root in quadratic equations.
2. Missing constant of integration '+ C' in indefinite integrals (-1 mark deduction immediately).
3. Incomplete geometric theorem statement before applying similarity ratios.
4. Inverting Cartesian signs in coordinate geometry distance or section formulas.
5. Forgetting to verify whether calculated x values satisfy original radical equations.
6. Missing boxed statement of the final result with units (e.g. [Area = 48 cm²]).
7. Overwriting or scratching errors instead of striking through with a single clean pen line.
