65 + 63 + 25 + 37
= ( 65 + 25 ) + ( 63 + 37 )
= 90 + 100
= 190
65 + 63 + 25 + 37
= ( 65 + 25 ) + ( 63 + 37 )
= 90 + 100
= 190
65 + 63 + 25 + 37
=( 65 + 25 ) + ( 63 +37 )
= 90 + 100
=190
65 + 63 + 25 + 37
= ( 65 + 25 ) + ( 63 + 37 )
= 90 + 100
= 190
65+63+25+37=(65+25)+(63+27)=90+90=180
nhầm nhé cho mình sửa:
65+63+25+37=(65+25)+(63+37)=90+100=190
65 + 63 + 25 + 37
= ( 65 + 25 ) + ( 63 + 37 )
= 90 + 100
= 190
