Question

Simplify using order of operation 10^2-2[12-(3-2)]

Answer 1

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
