Consider the following expression grammar. The seman$$tic rules for expression calculation are stated next to each grammar production.

E $->$ number E$.$val $=$ number. val $|$ E $\text{'}+\text{'}$ E E$(1).$val $=$ E$(2).$val $+$ E$(3).$val $|$ E $\text{'}\backslash$times $\text{'}$ E E$(1).$val $=$ E$(2).$val $\backslash$times E$(3).$val
