A concrete starting point
Multiply rectangular integer matrices with at most 64 rows and columns each. Test empty and single-cell inputs, rejecting ragged rows, incompatible dimensions and Boolean cells without modifying the matrices.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
