( 13 − 135 + 49 ) − ( 13 + 49 ) = 13 − 135 + 49 − 13 − 49 = ( 13 − 13 ) + ( 49 − 49 ) − 135 = 0 + 0 − 135 = − 135.

(13 – 135 + 49) – (13 + 49) = 13 – 135 + 49 – 13 – 49

= (13 – 13) + (49 – 49) -135 = 0 + 0 – 135

= -135

135 nha

Cho tớ cách làm

*Cách 1:

(13+49) - (13 - 135 + 49) = 62 - (-73)= 62 + 73 = 135

*Cách 2

(13 + 49) - (13 - 135 + 49)= 13 + 49 - 13 + 135 - 49 = (13-13)+(49-49)+135

= 0+ 135 = 135

\(=13-135+49-13-49\)

\(=\left(13-13\right)+\left(49-49\right)-135\)

\(=0+0-135\)

\(=-135\)

Bài làm

   ( 13 - 135 + 49 ) - ( 13 + 49 )

= 13 - 135 + 49 - 13 - 49

= ( 13 - 13 ) + ( 49 - 49 ) - 135

= 0 + 0 - 135

= -135

# Học tốt #

=13 - 135 + 49 - 13 - 49

=(13 - 13)  + (49 - 49) - 135

= 0 - 0 - 135

= -135

( 13 + 49) - ( 13 - 135 + 49)

= 13 + 49  - 13 + 135 - 49

= ( 13 - 13) + ( 49 - 49) + 135

= 0 + 0 + 135

= 135 

135

= (13 + 49) -13 + 135 - 49

= 13 + 49 - 13 + 135 - 49

= (13 -13) + (49- 49) + 135

=135

(-1075)-(29-1075)

= -1075-29+1075

= -1075+1075-29

= 0-29

= -29

(13-135+49)-(13+49)

= 13-135+49-13-49

= 13-13+49-49-135

= 0+0-135

= -135

13-135+49-13+(-49)

=(13-13)-135[ 49+(-49)]

=0-135+0

=135

hhọc tốt

\(13-135+49-13+\left(-49\right)\)

\(=\left(13-13\right)+\left[\left(-49\right)+49\right]-135\)

\(=0+0-135=-135\)

   13 - 135 + 49 - 13 + ( - 49 )

=  ( 13 - 13 ) + [ 49 + ( - 49 ] - 135

=          0       +        0            - 135

=                             - 135

Cảm ơn vì đã xem !!!!!!!!!!!

a,\(\left(5674-97\right)-5674=5674-97-5674=\left(5674-5674\right)-97=-97\)

b,\(-1075-\left(29-1075\right)=-1075-29+-1075=\left(-1075+1075\right)-29=-29\)c

\(\left(13-135+49\right)-\left(13+49\right)=13-135+49-13-49=-135\)

Nếu thấy mình làm đúng thì tick nha bạn,cảm ơn.

a) 18 + 29 - 158 - 29 - 18 = -158

b) 13 - 135 + 49 - 13 - 49 = -136

tick nha

a) =18+29+158-29-18=18-18+29-29+158=0+0+158=158

b) =13-135+49-13-49=13-13+49-49-135=0+0-135=-135

Tick nha
