Answer 1

Respuestas:

1) $19\left[\left(-4\right)-\left(-2\right)\right]+6+\left(-7\right)=-39$

2) $-\left(-14\right)-\left(-\left[\left(-2\right)\cdot \:3\right]+\left(-5\right)\left(-6\right)\right)+2=-20$

3) $\left(-8\right)\left(2\right)-15-\left[-4-2\right]-15\left(-3\right)=20$

4) $-2\left(\left(-7+5\right)\left(-3\right)+\left(-36\right)\cdot \:9\right)+1=637$

5) $\left(-3\right)\cdot \:2\left(\left[\left(-6\right)\cdot \:3\right]\cdot \:2+6\left(-4+3-2\right)\right)+\left(-72\right)\cdot \:9=-324$
