17.8 - 11.7 - 14.8 - 3.5 + 12.6
= 17.8 - 11.7 - 14.8 - 3.5 + 12.6= 17.8 - 11.7 - 14.8 - 3.5 + 12.6= 1.1 - 14.8 - 3.5 + 12.6= -13.7 - 3.5 + 12.6= -17.2 + 12.6= -4.6
Ответ: -4.6
17.8 - 11.7 - 14.8 - 3.5 + 12.6
= 17.8 - 11.7 - 14.8 - 3.5 + 12.6
= 17.8 - 11.7 - 14.8 - 3.5 + 12.6
= 1.1 - 14.8 - 3.5 + 12.6
= -13.7 - 3.5 + 12.6
= -17.2 + 12.6
