(144-97)-144
Giúp minh nha
Bài nay phải bỏ ngoac
[144-97]-144
[-145]-[18-145]
111+[-11+27]
bo ngoac roi tinh cac ban nha
[144 - 97] - 144
= 144 - 97 - 144
= 0 - 97
= -97
[-145] - [18 - 145]
= 145 - 18 + 145
= 0 - 18
= -18
111 + [-11 + 27]
= 111 - 11 + 27
= 100 + 27
= 127
(144-97)-144=144-97-144= -97
(-145)-(18-145)=(-145)-18+145=-18
111+(-11+27)=111-11+27=127
bỏ ngoặc rồi tính
1) -7264+(1543+7264)
2) (144-97)-144
3) (-145)-(18-145)
4) 111+(-11+27)
giúp mk nha các bn
1)-7264+(1543+7264)=-7264+1543+7264=(-7264+7264)+1543=0+1543=1543
2) (144-97)-144=144-97-144=(144-144)-97=0-97=-97
3) -145-(18-145)=-145-8+145=(-145+145)-8=0-8=-8
4)111+(-11+27)=111-11+27=100+27=127
1) 1543
2) -97
3) -18
4) 127
Nhớ tick mình nha !!!!! Đúng 100% đấy!!!!!
-7264 + 1543 + 7264
= -5721 +7264
= 1543
144 -97 -144
= 144 - 144 - 97
=-97
-145 - 18 + 145
=-163 + 145
= -18
sorry cau cuoi to khong lam duoc
tick nha

Giúp mình vớiiiiiiiiiii
tham khảo

bỏ ngoặc rùi tính;

=144-97-144
=144-144-97
=0-97

Các bạn chi minh 1 cau nha
Tính bỏ ngoặc kết quả phai chi tiet nha)
(-144)-[29-(+144)-(+144)
-144-[29-(+144)-(+144)]
= -144-(29-144-144)
= -144-29+144+144
= (144-144)+144-29
= 0+115=115
(-144)-[29-(+144)-(+144)]
=(-144)-[29-(-144)+(-144)]
=(-144)-29+144+144
=-173+144x2
=-173+288

Tran Thi Phuong Thao:
(-418) - {418 - [-418 - (-418 + 2017)]}
