Identify learning gaps before they become larger problems.

The student consistently mishandles the quotient rule for exponents and sign cancellation. In the multi-term rational-expression simplification involving a polynomial numerator divided by a monomial denominator, the last term was treated as multiplication by y instead of division, revealing a failure to produce a negative exponent. In single-term divisions such as (2/3)z⁵ ÷ (4/9)z² and (3/5)a⁴ ÷ (1/5)a², the original exponent was retained and the coefficient was mis-computed, indicating a broader difficulty with exponent subtraction and coefficient division.
