25,8+(0,2+6,25)
14,123+(5,71+7,29)
(27,194+6,82)+12,18
(7,88+3,153)-5,88
(73,185+18,68)-4,56
Fuga va rog!

Answer 1

16,3+(0,28+3,7)=(16,3+0,28)+3,7= 20,28
25,8+(0,2+6,25)=(25,8+0,2)+6,25= 32,25
14,123+(5,71+7,29)=(14,123+5,71)+7,29=27,123
(27,194+6,82)+12,18=27,194+(6,82+12,18)=46,194
(7,88+3,153)-5,88=7,88+(3,153-5,88)=5,153
(73,185+18,68)-4,56=73,185+(18,68-4,56)=87,305
