Answer :

Sure! Let's solve the expression step by step:

1. Simplify inside the parentheses:
[tex]\[ 2 - 3 - 45 \][/tex]

- Start by subtracting 3 from 2:
[tex]\[ 2 - 3 = -1 \][/tex]

- Then, subtract 45 from -1:
[tex]\[ -1 - 45 = -46 \][/tex]

So now the expression inside the parentheses is simplified to [tex]\(-46\)[/tex].

2. Substitute the simplified value back and continue the expression:
[tex]\[ (-46) + 10 - 5 \][/tex]

3. Add 10 to -46:
[tex]\[ -46 + 10 = -36 \][/tex]

4. Subtract 5 from -36:
[tex]\[ -36 - 5 = -41 \][/tex]

So, the final result of the expression [tex]\((2-3-45) + 10 - 5\)[/tex] is:
[tex]\[ \boxed{-41} \][/tex]
