Answer 2

Answer:

$\Huge \boxed{2}$

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for $\large \boxed{\textnormal{Parenthesis, Exponents, Multiply, Divide, Add, and Subtract}}$ the numbers from left to right. In fact, you can use stands for $\large\boxed{\textnormal{Please Excuse My Dear Aunt Sally!}}}$.

First, you do is parenthesis.

$\displaystyle (4-5)-(13-18+2)$

$\displaystyle (4-5)=-1$

$\displaystyle -1-(13-18+2)$

$\displaystyle 13-18=-5$

$\displaystyle -5+2=-3$

$\displaystyle -1-(-3)$

Next, add the numbers from left to right.

$\displaystyle -1-(-3)=-1+3=\boxed{2}$

$\bigstar\Large\boxed{\textnormal{The final answer is \boxed{2}}}}\bigstar$

I'd choose (d) 2.
