Answer :

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].
