giúp tớ với

Answer 1

\(2\left(-2+1\right)+5-\left(9-1+20\right)-\left(1+102\right)\)

\(=2\cdot\left(-1\right)+5-28-103\)

\(=-2+5-28-103\)

\(=-128\)

Answer 2

= 2.(-1) + 5 - 28 - 103

= -2 + 5 - 28 - 103

= -128

Answer 3

`2(-2+1)+5-(9-1+20)-(1+102)`

`=2.(-1)+5-(8+20)-103`

`=-2 + 5-28-103`

`= 3-28-103`

`= -25- 103`

`= -128`
