- $P \times Q$ means ' $P$ is the brother of $Q$ '
- $P - Q$ means ' $P$ is the sister of $Q$ '

Cevap

Cannot be determined, as the gender of

O

is not specified in the given expression.

Tracing the expression shows that

J

is the mother of

K

K

is the father of

N

, and

N

is the father of

O

. This makes

J

the great-grandmother of

O

, which means

O

is the great-grandchild of

J

. Since

O

is the terminal node in

N + O

, no operation defines

O

's gender. Therefore,

O

could be either a great-grandson or a great-granddaughter, making the exact relationship impossible to determine.
