Решите примеры: (-13 + 11) - (-4 + 7) = -108 - (-41 - 53) = (-3,14 + 2,71) - (-4,7 +...

Решите задачу:

$( - 13 + 11) - ( - 4 + 7) \\ - 2 - 3 = -5$
$( - 3.14 + 2.71) - ( - 4.7 + 1.8) \\ - 0.43 + 2.9 = 2.47$
$- 8 \frac{2}{11} - ( - 3 \frac{5}{22} + 7 \frac{6}{11}) = \\ - 8 \frac{4}{22} + 3 \frac{5}{22} - 7 \frac{12}{22} = \\ -15 \frac{16}{22} + 3 \frac{5}{22} = -12\frac{1}{2}$

$- 108 - ( - 41 - 53) = \\ - 108 + 41 +53 = \\ - 108 +94 = - 14$
