Пожалуйста помогите. 1) 36:(-4)-65-(-5)*(-4). 2) (-7-9*7):(46-53). 3) -16:4*(-57-25+79)....

Решение:
1) $\frac{360}{-4} - 65 - (-5) *(-4) = -90-65-20 = 175$

2) $(-7-9*8) : (46-53) = (-7-72) : -7 = \frac{79}{7} = 11 \frac{2}{7}$

3) $\frac{-60}{4} * (-57 -25+79) = \frac{-3 * (-60)}{4} = \frac{180}{4} = 45$

4) $(4 * (-8)+27-43) : -6 = (-32-43+27) : -6 = \frac{48}{6} = 8$

5) $-36 : (27-18)+3*(-3) = -36 : 9 + (-9) = 0$

6) $72:((-5)*5-19+36)= 72:(-25-19+36) = \frac{72}{-8} =-9$

7) $8-18:2*(37-45) = 8 - 9*(-8) = 80$

8) $-70+(-8*2-4):4 = -70-20:4 = \frac{-90}{4} = 22.5$

9) $(-5)*(-3)-(-75)+45:(-5) = 15+75-9 = 81$

10) $-64:(2*4)+3-37 = \frac{-64}{8} +3-27 = -8-24=-32$
