38,25 - 11,64 - 18,25 + 9,93 + 21,64
= 38,25 - 18,25 + 21,64 - 11,64 + 9,93
= 20 + 10 + 9,93
= 30 + 9,93
= 39,93
=(38,25 - 18,2) + (21,64-11.64) + 9,93
= 20 + 10 +9,93
= 39.93
= (38,25-18,25)+(21.64-11,64)+9,93
=20+10+9,93
=39,93
38,25 - 11,64 - 18,25 + 9,93 + 21,64
= 38,25 - 18,25 + 21,64 - 11,64 + 9,93
= 20 + 10 + 9,93
= 30 + 9,93
= 39,93
38,25 - 11,64 - 18,25 + 9,93 + 21,64
= 38,25 - 18,25 + 21,64 - 11,64 + 9,93
= 20 + 10 + 9,93
= 30 + 9,93
= 39,93
= 39,93 chỉ biết thế thôi
