V (0, + 6) F (0, + 10)

0 \cdot V F, 0, 0, 10 + 0 \cdot 6 V F, 610

求解步骤

V (0, + 6) F (0, + 10)

= (0, + 6) (0, + 10) V F

乘开

(0, + 6) (0, + 10) : 0, 0, 0, 10 + 0 \cdot 6, 610

= V F (0, 0, 0, 10 + 0 \cdot 6, 610)

乘开

V F (0, 0, 0, 10 + 0 \cdot 6, 610) : 0 \cdot V F, 0, 0, 10 + 0 \cdot 6 V F, 610

= 0 \cdot V F, 0, 0, 10 + 0 \cdot 6 V F, 610
