10 (15+20) + {[-6(15 + -6) -4 (7)] + -6}+10

Answer 1

Respuesta:

1) 12-36+15×(-3)-6×(-9)=

-24+15×(-3)-6×(-9)=

-9×(-3)-6×(-9)=

27-(-54)=

27+54=

81

2) 10×(15+20)+{[-6×15+(-6)-4×(7)]+(-6)}+10=

10×35+{[-6×15+(-6)-28]+(-6)}+10=

350+{[-90-6-28]-6}+10=

350+{[-96-28]-6}+10=

350+{[-124]-6}+10=

350+{-130}+10=

350-130+10=

220+10=

230
