💡 Analysis & Explanation

[Expression Decomposition Strategy] ▼

To map the genealogical tree accurately, we decode the string 'M + N × O - P ÷ Q' progressively from right to left, anchoring on Q.

[Link 1] ▼

'P ÷ Q' establishes that P is strictly the male Father of Q.

[Link 2] ▼

'O - P' signifies that O is the male Brother of P. Therefore, O is the paternal uncle (Father's brother) to Q.

[Link 3] ▼

'N × O' dictates that N is the female Wife of O. Thus, N is the aunt (Father's brother's wife) to Q.

[Link 4] ▼

'M + N' translates to M being the female Mother of N. Consequently, M is the mother-in-law to O.

[Final Synthesis] ▼

Tracing the complete path from Q back to M: M is the mother of the woman (N) who is married to the brother (O) of Q's father (P).

Conclusion ▼

Functionally, M is the Father's brother's wife's mother.
