Answer 1

Solución:

-5+5:-5.-1-(-3+(2.-1 +8)-

$\frac{-5+5}{-5-1-\left(-3+\left(2-1+8\right)\right)}$

$=\frac{-5+5}{-5-1-\left(-3+2-1+8\right)}$

$=\frac{0}{-5-1-\left(2+8-3-1\right)}$

$=\frac{0}{-12}$

$=-\frac{0}{12}$

$=-0$

$=0$

4.-3-12 - 8+ 9.-2

$=1-12-8+9-2$

$=-11-8+9-2$

$=-19+9-2$

$=-10-2$

$=-12$

5.-2+3.-8.-15.0+.9

$5-2+3-8-15+0.9$

$=-16.1$

6--3+-2--8+2

$6-3-2-8+2$

$=3-2-8+2$

$=1-8+2$

$=-7+2$

$=-5$

-7:-1 +2:-2-8.4

$-\frac{7}{-1}+\frac{2}{-2}-8.4$

$=-\left(-7\right)-1-8.4$

$=7-1-8.4$

$=-2.4$

(2-4).3 - (5+2)

$\left(2-4\right)\cdot \:0.3-\left(5+2\right)$

$=-0.6-\left(5+2\right)$

$=-0.6-7$

$=-7.6$

-5(-4[-(-2+8)-(-3 +2)]

$-5-4\left[-\left(-2+8\right)-\left(-3+2\right)\right]$

$=-5-4\left(-5\right)$

$=-5-\left(-20\right)$

$=15$
