In a certain code language,
'R + T' means 'R is the sister of T'.
'R - T' means 'R is the father of T'.
'R * T' means 'R is the wife of T'.
'R ÷ T' means 'R is the mother of T'.

Based on the above, how is H related to E if 'D−E∗F−G+H÷I+J'?

Let's parse the relationship expression step by step:
D−E→ D is the father of E.

E∗F→ E is the wife of F (E is female, F is male).

F−G→ F is the father of G.

G+H→ G is the sister of H.

H÷I→ H is the mother of I (H is female).

I+J→ I is the sister of J.

Let's find the relation of H to E:

F is the father of G.

G is the sister of H, which means F is also the father of H.

E is the wife of F, so E is the mother of all of F's children (G and H).

Since H is a daughter of E and F (as H is female because H ÷ I means H is a mother).

Thus, H is the Daughter of E.
