12

$[(9 \cdot 2) - (3 \cdot 4)] \cdot 2$ $[(9*2) -(3*4)] *2$

$(18 - 12) \cdot 2$ $(18 - 12)*2$

$6 \cdot 2$ $6*2$

12

The result is $12$ $12$ .

First, do the steps on the innermost parentheses, then the outer ones:

$= [(9 \times 2) - (3 \times 4)] \times 2$ $color(white)=[(9xx2)-(3xx4)]xx2$

$=[stackrel(18) overbrace((9xx2)) - stackrel(12) overbrace((3xx4))] xx2$

$=[18-12]xx2$

$=[stackrel6 overbrace(18-12)]xx2$

$=6xx2$

$=stackrel12 overbrace(6xx2)$

$=12$
