If $$+$$ means $$-$$, $$-$$ means $$\times$$, $$\times$$ means $$\div$$, and $$\div$$ means $$+$$, then what will be the value of following expression?
$$13 - 3 + 15 \times 3 \div 5 = ?$$
From the question,       Â
$$+$$ means $$-$$, $$-$$ means $$\times$$, $$\times$$ means $$\div$$ , $$\div$$ means $$+$$ then   Â
$$13-3 + 15\times 3\div 5$$
Now substituting the symbol as per the given question,
$$\Rightarrow 13\times 3 - 15 \div 3Â + 5 $$
$$\Rightarrow 39 - 5 + 5 $$
$$\Rightarrow 44 -5 $$
$$\Rightarrow 39 $$ Ans
