Answer:
32
Step-by-step explanation:
Since all the operations are + signs, there is no change in the value of the first equation and the second equation. All that happens is the transfer of the bracket from 32 and 45 to 12 and 32 since all three numbers should remain in the equation. Thus, 12+(32+45) = 12+32+45 = (12+32)+45
