16道……最后再补到35分
一定要约到最简化……
(1) -1/3+15.5+(-2/3)
(2) 4.7-3.4-(-8.5)-(+1/2)
(3) 2.5-4+(-1/2)
(4) 1/2+(-2/3)-(-4/5)+(-1/2)
(5) 0.4-(-1/4)+1/6
(6) 0.5+(-1/4)-(-2.75)+1/2
(7) -2/3+(-1/6)-(-1/4)-1/2
(8) 3/5-3/2+(-11/4)+13/4
(9) 31+(-5/4)+0.25
(10) -21.6+3-7.4+(-2/5)
(11) (-6/5)-7-(-3.2)+(-1)
(12) 3/4-(-11/6)+(-7/3)
(13) 7又5/6+(-5又1/3)+2又1/4+(-4又3/4)
(14) (+3又5/6)+(-5又1/7)+(-2又1/6)+(-32又6/7)
(15) (-2/3)-(0.2-0.1)-(-5/6)
(16) -4.7+1.8-2.9+4.32

Answer 1

你能打出来那么烦的东西.还不如慢慢算呢.如果你是初一的学生.那这些很简单的,自己多算算,真不会的再问.
