Do the work. And which one do you think it is..

105 - 32 * (5 + 2) =
105 - 32 * 8 =
105 - 256 =
- 151 (not this one)

80/2 * (4 + 6) + 2 =
40 * 10 + 2 =
400 + 2 = 
402 (nope)

3 * [ 6 + 2 * (7 - 3) ] =
3 * [ 6 + 2*4] =
3 * [ 6 + 8 ] =
3 * 14 = 42 (BINGO)

[ 102 - (10 - 2) * 9 ] + 12 =
[ 102 - 8 * 9 ] + 12 = 
[ 102 - 72 ] + 12 =
30 + 12 = 42 (BINGO)
