Q10a

Consider the following grammar for arithmetic expressions using binary operators $-$ and $/$ which are not associative $E \rightarrow E -T\mid T$ $T \rightarrow T/F\mid F$ $F \rightarrow (E) \mid id$ ($E$ is the start symbol) Is the grammar unambiguous? Is so, what is the relative precedence between $-$ and $/$? If not, give an unambiguous grammar that gives $/$ precedence over $-$.
