= 27 + 514 - 486 + 73
=(27 + 73) +(514 - 486 )
= 100 + 28 =128
(27+514)-(486-73)
=541-413
=128
mình trước nha
\(\text{(27+514)-(486-73)}\)
\(=27+514-486+73\)
\(=\left(27+73\right)+\left(514-486\right)\)
\(=100+28\)
\(=128\)
( 27 + 514 ) - ( 486 - 73 )
= 541 - 413
= 128
( 27 + 514 ) - ( 486 - 73 )
= 27 + 514 - 486 + 73
= 27 + 514 + ( - 486 ) + 73
= ( 27 + 514 + 73 ) + ( - 486 )
= 614 + ( - 486 )
= 128
Chúc bạn học tốt !
(27+514)-(486-73)
=27+514-486+73
=(514-486)+(73+27)
=28+100
=128
(27 + 514 ) - ( 486 - 73)
=27 + 514 - 486 + 73
= ( 27 + 73 ) + ( 514 - 486)
= 100 + 28
