Explanation:

Step1: Solve innermost parentheses

For the expression $[13-(10 - 6)]-[6-(5 - 10)]$, first solve $10 - 6=4$ and $5 - 10=- 5$. So it becomes $[13 - 4]-[6-(-5)]$.

Step2: Solve the brackets

$13 - 4 = 9$ and $6-(-5)=6 + 5=11$. Then the expression is $9-11$.

Step3: Calculate the final result

$9-11=-2$.
