(-1075) - (29 - 1075) = - 1075 - 29 + 1075 = - 29

(-1075)-(29-1075)

=-1075-29+1075

=(-1075+1075)-29=0-29=-29

\(=-1075-29+1075-11=-40\)

\(\left(-1075\right)-\left(29-1075\right)+\left(-11\right)\\ =\left(-1075\right)-29+1075-11\\ =\left(-1075+1075\right)-\left(29+11\right)\\ =0-40\\ =-40\)

\(\left(-1075\right)-29+1075+\left(-11\right)\\ =\left(-1075\right)+1075-29+\left(-11\right)\\ =-29+\left(-11\right)\\ =-40\)

( - 1075 ) - ( 29 - 1075 )

= - 1075 - 29 + 1075

= ( - 1075 + 1075 ) - 29

= 0 - 29

= - 29

(-1075) – (29 – 1075) = (-1075) – 29 + 1075

= (-1075 + 1075) – 29 = 0 -29 = -29

\(A=\left(4567-97\right)+\left(-1075\right)-4567-\left(29-1075\right)\)

\(A=4567-97-1075-4567-29+1075\\ A=\left(4567-4567\right)+\left[\left(-1075\right)+1075\right]-97-29\\ A=0+0-97-29\\ A=0-97-29\\ A=-97-29\\ A=-126\)

a) -97

b) -29

Bấm đúng nha , mình là người đầu tiên nè

a. (5674 - 97) - 5674

= 5674 - 5674 - 97

= -97

b. (-1075) - (29 - 1075)

= -1075 + 1075 - 29

= -29

(-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

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) ( 5674 - 97 ) - 5674

= ( 5674 - 5674 ) - 97

= 0 - 97

= -97

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

\(=5674-97-5674\)

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

\(=0-97\)

\(=-97\)

b) \(\left(-1075\right)-\left(29-1075\right)\)

\(=\left(-1075\right)-29+1075\)

\(=\left[\left(-1075\right)+1075\right]-29\)

\(=0-29\)

\(=-29\)

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

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