\(\left|-127\right|-18\left(5-6\right)=127-18.\left(-1\right)=127+18=145\)

127 - 18 .(5+6) =127 - 18 . 11 =127 - 198=127 + (-198)= -(198 - 127) = (-71)

Ta có \(\left|-127\right|-18.\left(5-6\right)\)
\(=127-18.\left(-1\right)\)
\(=127+18\)
\(=145\)

a, 127 - 18 ( 5+6 ) =127 - 18 x11 = -71
b, 26 + 7(4-12) = 26 + 7 x (-8) =-30
TK nha!
a) 127 - 18.(5+6)
= 127 - 18.11
= 127 - 198
= -71
b) 26 + 7.(4-12)
= 26 + 7.(-8)
= 26 + (-56)
= -30

a)\(\left(-3\right).8.\left(-2\right).5=\left(-3\right).\left(-2\right).8.5\)
\(=6.40=240\)
b)\(127-18.\left(5+6\right)=127-18.11\)
\(=127-198=-71\)
c)\(125-\left(-75\right)+32-\left(48+32\right)=125+75+32-48-32\)
\(\left(125+75\right)+\left(32-32\right)-48=200-48=152\)
d)\(3.\left(-4\right).2+2.\left(-5\right)-20=-12.2+2.\left(-5\right)-20\)
\(=\left(-12-5\right).2-20=-17.2-20=-140-20=-160\)
Chúc bạn học tốt
| - 127 | - 18 ( 5 - 6 )
= | - 127 | - 18 ( - 1 )
= | - 127 | - ( - 18 )
= 127 + 18
= 145
|-127|-18.(5-6)
=127-18.(5-6)
=127-18.(-1)
=127-(-18)
=127+18
=145
