Sure, let's solve the expression step by step:
1. Innermost Operation First:
Start with the innermost parenthesis:
[tex]\[
4890 - 2000 = 2890
\][/tex]
2. Substitute the Result:
Replace the parenthetical expression with the result obtained:
[tex]\[
36450 - 18730 + 2890
\][/tex]
3. Perform Subtraction and Addition from Left to Right:
Begin with the subtraction:
[tex]\[
36450 - 18730 = 17720
\][/tex]
4. Add the Result of the First Subtraction to the Remaining Number:
[tex]\[
17720 + 2890 = 20610
\][/tex]
So, the final result of the expression [tex]\(36450 - 18730 + (4890 - 2000)\)[/tex] is [tex]\(\boxed{20610}\)[/tex].
