MATH.17:8 - Common Anti-Patterns and How to Avoid Them

Inferring closure from individual permission. The two flips in :5.1 each meet the step condition but fail it when composed. Decide whether the requirement concerns a step, a sequence or the whole input-output change, and construct the corresponding collection.

Moving a transformation through composition without its law. Repeating each stage twice changed the answer in :5.2. Derive the transformation equation before using it to reorganize a sequence.

Demanding the wrong preservation law. Polynomial differentiation supplies a useful operator through linearity and the product rule. Choose the law from the intended transformation instead of requiring every operator to preserve multiplication or composition.
