Question 65

If $$+$$ meams $$\div,\div$$ means $$-$$, $$-$$ means $$\times$$, and $$\times$$ means $$+$$ then find the value of the following expression: $$5-(13-4+2\div6\times15\div5)$$

$$+\rightarrow\div$$
$$\div \rightarrow -$$
$$-\rightarrow \times$$
$$\times \rightarrow +$$

$$5-(13-4+2\div6\times15\div5)$$

$$5\times(\left(13\times\left(4\div2\right)\right)-6+15-5)$$

$$5\times(\left(13\times2\right)-6+15-5)$$

$$5\times(26-6+15-5)$$

$$5\times30$$

$$150$$
