21+21+19+19=80
109 you can plus like this: (19+1)+20+20+(1+1+18)+4+25
25 + 15 + 21 + 10 + 11 = 82
(25 +21) * 2 = 92 25 + (21 * 2) = 67
-4/25 + 19/25 = 15/25 = 3/5
That depends on the plus or minus value of 25 but --21 is the same as +21

109 you can plus like this: (19+1)+20+20+(1+1+18)+4+25
25 + 16 + 19 = 60
(21)3 -(19)3 (21)2+(19)2+(399)
25 + 21 = 46
21 + 39 + 45 + 25 = 130
-25
25 + 15 + 21 + 10 + 11 = 82
-19 + 6 - 25 = -38
22 + 24 + 28 + 25 + 20 + 19 = 138
