Given the expression:

$10^2-2\lbrack12-(3-2)\rbrack$

We start from the parenthesis inside the brackets. We know that 3-2=1, then:

$10^2-2\lbrack12-(3-2)\rbrack=10^2-2\lbrack12-(1)\rbrack=10^2-2\lbrack11\rbrack$

now, we have that 10^2=100 and 2*11 =22, then:

$10^2-2\lbrack11\rbrack=100-22=78$

therefore, the result of simplifying the expression is 78
