` ( 20,18 . 20,19 + 20,19 .20,10 + 20,20 . 20,21 ) . ( 1+1/3 - 1 1/3 )`
`= ( 20,18 . 20,19 + 20,19 .20,10 + 20,20 . 20,21 ) . ( 4/3 - 4/3 )`
`= ( 20,18 . 20,19 + 20,19 .20,10 + 20,20 . 20,21 ) . 0`
Vì bất cứ số nào nhân với `0` cũng bằng `0` nên
Giá trị của biểu thức là : `0`
`(20,18.20,19+20,19.20,10+20,20+20,21)(1+1/3-1 1/3)`
`=(20,18.20,19+20,19.20,10+20,20+20,21)(3/3+1/3-(1.3+1)/3)`
`=(20,18.20,19+20,19.20,10+20,20+20,21)(4/3-4/3)`
`=(20,18.20,19+20,19.20,10+20,20+20,21)0`
`=A.0=0` ( Bất kì số nào nhân với không vẫn là $0$ )
