642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 1000
Nhớ tk mình nha!
642 – 29 + 329 – 42 +100
= (642 – 42) + (329 – 29) + 100
= 600 + 300 + 100
= 1000
642-29+329-42+100
= ( 642 - 42 ) + ( 629 - 29 ) + 10
= 600 + 600 + 100
= 1200 + 100
= 1300
642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 1000
(642-42)+(329-29)=600+300+100=1000
642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 900 + 100
= 1000
Tình bằng cách thuận tiện nhất: 642-29+329-42+100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 900 + 100
= 1000
=(642-42)+(329-29)+100.
=600+300+100.
=1000.
642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 1000
642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 29 ) + 100
= 600 + 300 + 100
= 900 + 100
= 1000
642 - 29 + 329 - 42 + 100
= ( 642 - 42 ) + ( 329 - 39 ) + 100
= 600 + 300 + 100
= 1000
