问题描述：
(1995×1996-1)÷(1995+1994×1996)
37-0.37×8.28-3.7×0.172
1.919×2003+22×2.003+5.9×20.03
有算式啊
答
1
0
2.003*(1919+22+59)=4006
答
(1995×1996-1)÷(1995+1994×1996) ＝ 1
37-0.37×8.28-3.7×0.172 ＝ 34.5728
1.919×2003+22×2.003+5.9×20.03 = 4006
答
(1995×1996-1)÷(1995+1994×1996)
=[1995*(1995+1)-1]÷[1995+(1995-1)(1995+1)]
=(1995*1995+1995-1)÷(1995*1995+1995-1)
=1
37-0.37×8.28-3.7×0.172
=37-3.7*(0.828+0.172)
=37-3.7
=33.3
1.919×2003+22×2.003+5.9×20.03
=2003*(1.919+0.022+0.059)
=2003*2
=4006
