-1/4-1/2=
125+(-5)=
2.9-2.7=
-32-(38)=
74(-74)=

Answer 1

Explicación paso a paso:

$- \frac{2}{3} - ( \frac{1}{4} ) = \\ \\ - \frac{2}{3} - \frac{1}{4} = \frac{ - 8 - 3}{12} = - \frac{11}{12}$

$- 5 + ( - 3) = - 5 - 3 = - 8$

$- 8 \times 75 - 13 \times 1 \\ - 600 - 13 = - 613$

$- 4 \times 2 + ( - 8) = \\ - 8 - 8 = - 16$

$- \frac{1}{4} - \frac{1}{2} = \frac{ - 1 - 2}{4} = - \frac{3}{4}$

$125 + ( - 5) = 125 - 5 = 120$

$2 \times 9 - 2 \times 7 \\ 18 - 14 = 4$

$- 32 - (38) \\ - 32 - 38 = - 70$

$74( - 74) = - 5476$
