16 + 6 + 26 + 14 + 11 + 13 + 4
= (16 + 11 + 13) + (6 + 4) + (26 + 14)
= (27 + 13) + 10 + 40
= 40 + 50
= 90

ok
16 + 6 + 26 + 14 + 11 + 13 + 4 = ( 16 + 4 ) + ( 6 + 14) + ( 11+ 13 + 26) = 20 + 20 + 50 = 90
16 + 6 + 26 + 14 + 11 + 13 + 4
= ( 16 + 4 ) + ( 6 + 14) + ( 11 + 13 + 26 )
= 20 + 20 + 50
= 90
K mk nha
16 + 6 + 26 + 14 + 11 + 13 + 4
