In a certain code language,
$A+B$ means '$A$ is the Brother's Wife of $B$ '
$A-B$ means '$A$ is the Sister of $B$ '
$A\times B$ means '$A$ is the Wife of $B$ '
$A÷B$ means '$A$ is the Daughter of $B$ '

Based on the above, how is $G$ related to $Q$ if '$G+K-L÷M\times Q$ '?

To find the relation between $G$ and $Q$ from the expression $G+K-L÷M\times Q$, we break it down step-by-step from right to left:
1. $M\times Q⟹M$ is the wife of $Q$. This means $M$ is female and $Q$ is male (husband and wife).
2. $L÷M⟹L$ is the daughter of $M$. Since $M$ is married to $Q$, $L$ is also the daughter of $Q$.
3. $K-L⟹K$ is the sister of $L$. Therefore, $K$ is also a daughter of $Q$ and $M$.
4. $G+K⟹G$ is the brother's wife of $K$. Since $K$ is the daughter of $Q$, $K$ 's brother must be the son of $Q$. $G$ is married to this brother, which makes her the wife of $Q$ 's son.

Thus, $G$ is the Son's wife of $Q$.
