Answer 1

Ответ:

А

$7.008 - 2.98 + 2.16 - 0.469 - 4.306 - 0.26 + 0.095 = 7.008 - 0.82 - 4.306 - 0.634 = 1.248$

В

$9.0008 - 0.628 - 1.9854 - 0.26 - 1.874 + 3.36 - 2.461 = 9.0008 - 2.6134 - 1.235 = 5.1524$

Г

$18.27 - 2.374 + 40 - 31.8 - 0.029 + 0.00129 + 0.00067 = 58.27 - 2.374 - 31.8 - 0.02704 = 26.47 - 2.40104 = 24.06896$

Б

6.003+2.0005-3.0494(6.8-5.9252-0.0095)=8.0035-3.0494*0.8653=8.0035-2.63864582=5.36485418
