The answer is 672.
19 + (44 + 23) = (19 + 44) + 23
16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
11 + (19 + 6) = 36(11 + 19) + 6 = 36So they are both equal. The brackets make no difference in this case.
22 + 24 + 28 + 25 + 20 + 19 = 138
The answer is 672.

19 + 19 + 4 + 4 = 46
21+21+19+19=80
19+19+9 = 47
19 + (44 + 23) = (19 + 44) + 23
25 plus 21 plus 19 is equal to 65.
16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
-36
19 plus 10 equals 29.
