Question

Помогите решить задание по математике номер три

Answer 1

$- 42 + 75 + ( - 14) + ( - 26) + 56 = - 42 + 75 - 14 - 26 + 56 = 131 - 82 = 49$

$12 + ( - 20) - ( - 11) - ( - 6) - 10 = 12 - 20 + 11 + 6 - 10 = 29 - 30 = - 1$

$3 \frac{5}{12} - ( - 1 \frac{1}{3} ) + ( - 4 \frac{3}{8} ) = 3 \frac{10}{24 } + 1 \frac{8}{24} - 4 \frac{9}{24} = 4 \frac{18}{24} - 4\frac{9}{24} = \frac{9}{24} = \frac{3}{8}$
