一、直接写出得数。(每题0.5分,共35分)。
17-6= 15-5= 14+2= 2+17=5+13= 15-3= 15-15= 10-7=
18+1= 4+11= 14-3=4+15=
7+3= 19-6= 6+10= 16-10=
0+17= 4+15= 8+11= 19-6=
11+6= 16-0= 6+2= 8-3=12+6= 17-6= 14+3= 0+14=
19-3= 19-4= 13+3= 18-5=
15+4= 16-5= 3+14= 17-5=
12+6= 17+2= 17-6= 16-5=
17-6= 12+3= 15-1= 15-3=12-2= 10+9= 17-6= 15-4=
16-12= 12+4= 19-9= 16-3=
12+7= 17-4= 2+15= 17-17=
6+3= 12+4= 15-2= 17-12=
19-11= 8+2= 16+1= 18-12=
4+13= 19-12= 4+5= 15-5=
5+13= 18-0=
2
2 二、在()填入合适的数。(每题1分,共25分。)
( ) - 8 =1 19- ( ) = 17 5 + ( ) = 18
12 - ( ) = 10 ( ) + 16 = 16 ( ) - 6 = 4
19- ( ) = 13 14 + ( ) = 18 12 - ( ) = 2
( ) + 14 = 16 ( ) - 6 =1 17 - ( ) =5 14 + ( ) = 19 12 - ( ) = 12 ( ) + 16 = 16
( ) + 5 = 10 18 - ( ) = 11 ( ) - 6 =4
7 + ( ) = 18 19 - ( ) = 11 6+()=16 16 - ( ) = 13 18 - ( ) = 13 18 - ( ) = 8
11+5-( )=11 三、加减混合运算。(每题2分,共20分. )
18+2-2= 12+4-3= 19-12+6= 4+6-8=
17-2-5= 10+6-5= 4+15-6= 15-4-2=
12+3-1= 11+5-6= 四、在○里填“>”、“<”或“=”。(每题2分,共20分.)
6+4○12 6+4+3○19-5 4+6○8+2+0
18○11+7 7+3○19-3-5 4+6-5○18-8
11+3○17-7+4 13○16-3 16+3○19-3
20○10+9
