二、 笔算(45分,每题1.5分)
3 + 95 = 72 + 5 = 25 + 4 = 35 - 3 = 39 - 2 = 3 + 34 = 74 + 4 = 87 - 5 = 46 - 3 = 69 - 8 = 5 + 12 = 67 - 6 = 62 + 3 = 3 + 73 = 87 - 2 = 18 - 3 =
97 - 3 = 12 + 6 = 96 - 5 = 5 + 54 = 24 - 2 = 43 + 5 = 16 - 4 = 7 + 51 =
55 - 2
52 + 4 =
91 + 8

(5)36 +40 - 5= (6)7 + 8-5= (7)63-30+ 10= (8)59 + 5-10=
(9)56 + 10-7= -2=
(13)37 + 10-5= 40=
(17)32-0+56= (20)32+10+9=
(10)11-( 9 + 1)= (11)5 3+ 4-8= (12)91 + 1(14)92 + 7-2= (15)19-19 + 18= (16) 39+30- (18)17+40-30= (19)26+9+11=
