Giải ra nha các bạn!!!

b)125+|-25|=125+25=150

c)|-26|+|-34|=26+34=60

Bài toán 1: Tính.

a) (-34) + (-91) + (-26) + (-99)

= [(-34) + (-26)] + [(-91) + (-99)]

= -60 + (-190)

= -250 

b) 125 + |-25|

= 125 + 25

= 150

c) |-26| + |-34|

= 26 + 34

= 60

d) |-82| + (-120)

= -82 + (-120)

= -202

e) (-275) + |-115|

= -275 + 115

= -160

f) (-34) + |-34|

= (-34) + 34

= 0

a: =34x(-100)=-3400

b: =41(-76-24)=-4100

c: =-24(125-225)=2400

d: =26(-237+137)=-2600

e: =25(-63+23)=25x(-40)=-1000

a) \(-75+\left(-325\right)+\left|-45\right|-\left(-125\right)\)

\(=-75-325+45+125\)

\(=\left(45+125\right)-\left(75+325\right)\)

\(=170-400\)

\(=-230\)

b) \(62+\left|128\right|-\left|-155\right|-\left|70\right|\)

\(=62+128-155-70\)

\(\Leftrightarrow190-225\)

\(=-35\)

c) \(815+\left[95+\left(-815\right)+\left(-45\right)\right]\)

\(=815+95-815-45\)

\(=\left(815-815\right)+\left(95-45\right)\)

\(=0+50\)

\(=50\)

d) \(5+\left(-7\right)+9+\left(-11\right)+...+25+\left(-27\right)\)

\(=\left(5-7\right)+\left(9-11\right)+...+\left(25-27\right)\)

\(=-2-2-...-2\)

\(=-2.11\)

\(=-22\)

e) \(34+35+36+37-24-25-26-27\)

\(=\left(34-24\right)+\left(35-25\right)+\left(36-26\right)+\left(37-27\right)\)

\(=10+10+10+10\)

\(=40\)

Ths ban

a) (-34) + (-91) + (-26) + (-99)

= [(-34) + (-26)] + [(-91) + (-99)]

= (-60) + (-190)

= - 250 

a) ( - 34 ) + ( - 91 ) + ( - 26 ) + ( - 99 )

= [ ( - 34 ) + ( - 26 ) ] + [ ( - 91 ) + ( - 99 ) ]

= - 60 + ( - 190 )

= - 250

Cbht

\(a,\left(-34\right)+\left(-91\right)+\left(-26\right)+\left(-99\right)\)

\(=\left[\left(-34\right)+\left(-26\right)\right]+\left[\left(-91\right)+\left(-99\right)\right]\)

\(=\left(-60\right)+\left(-190\right)\)

\(=-250\)
