Let's simplify the given expression step by step:
The expression is [tex]\((4-5)-(13-18+2)\)[/tex].
First, we simplify the expression inside the parentheses:
[tex]\[ 13 - 18 + 2 \][/tex]
Calculate [tex]\(13 - 18\)[/tex]:
[tex]\[ 13 - 18 = -5 \][/tex]
Now, add 2 to the result:
[tex]\[ -5 + 2 = -3 \][/tex]
So, the expression inside the parentheses simplifies to -3.
Next, we need to simplify the entire expression:
[tex]\[ (4 - 5) - (-3) \][/tex]
Calculate [tex]\(4 - 5\)[/tex]:
[tex]\[ 4 - 5 = -1 \][/tex]
Now, subtract [tex]\(-3\)[/tex]:
[tex]\[ -1 - (-3) \][/tex]
Remember, subtracting a negative number is the same as adding the positive equivalent:
[tex]\[ -1 + 3 = 2 \][/tex]
Therefore, the simplified value of the given expression is [tex]\(2\)[/tex].
So, the correct answer is:
[tex]\[ \boxed{2} \][/tex]
