( 27 + 65 ) + ( 346 - ( - 27 ) - 65
= 92 + 373 - 65
= 465 - 65
= 400
(27 + 65) + (346 --27 - 65)
= (27 + 65) + (346 + 27 - 65)
= (27 + 346 + 27) + ( 65 - 65)
= 400 + 0
= 400
(27+65)+(346-27-650
=27+65+346+27-65
=(27-2)+(65-65)+346
=0+0+346=346

Ta có: (27 + 65) + (346 - 27 - 65)
= 92 + 254
=346
Đs: 346
