四年级十道竖式计算

640÷80= 15*5= 23*3= 12*2*5= 480÷80= 16*5= 27*3= 90÷15= 48÷4= 640÷16= 39÷3= 24*20= 32*3= 48÷16= 12*8= 27*3= 56÷14= 24÷8= 14*2= 83-45= 560÷80= 96÷24= 40÷20= 40*30= 37+26= 76-39= 605+59= 30*23= 12*8= 27+32= 48+27=

10÷6= 5÷4= 100÷30= 9÷8= 66÷44= 132÷123 8÷10= 65÷72= 980000÷1000000000= 32÷48=

A、列竖式计算: (1)350÷60 (2)780÷26 (3)66*23 (4)895÷35 (5)378÷42 B、混合运算: (1)480-180+60 (2)480-(180+60) (3)360÷40*9 (4)360÷(40*9) (5)90-40*2

1.25 -15 -80 = 10 -80 = 2.26 -6 -64 = 20 -64 = 3.27 + 3 -48 = 30 -48 = 4.28 + 12 -32 = 40 -32 = 5.29 + 21 -16 = 50 -16 = 6.30 + 30 + 0 = 60 + 0 = 7.31 + 39 + 16 = 70 + 16 =8.32 + 48 + 32 = 80 + 32 = 9.33 + 57 + 48 = 90 + 48 = 10.34 + 66 + 64 = 100

526÷80= 630÷60= 600÷30=530÷50= 640÷40= 500÷70=510÷90= 850÷50= 800÷40=192÷32= 192÷39= 97÷23= 334÷41= 85÷38= 240÷57=210÷42= 274÷29= 450÷63=362÷48= 510÷87= 510÷82= 265÷59=10-4.4= 6+6.6= 9.5-2.7= 1-0.55= 3.7+4.8=

四年级竖式计算 举例如下:999 + 1111 = 2110123+1289=1412327+1845=21721111 199 = 91270-25=45123 89 = 3412 * 13 = 15611 * 67 = 73799 * 9 = 891123 * 7 = 86128.63 0.04 = 28.59104.5 + 18.85 = 123.355.235 4.495 = 0.74759 ÷ 33 = 23867 ÷ 85 = 10.2630 ÷ 24 = 26.25

. 3/7 * 49/9 - 4/3 2. 8/9 * 15/36 + 1/27 3. 12* 5/6 2/9 *3 4. 8* 5/4 + 1/4 5. 6÷ 3/8 3/8 ÷6 6. 4/7 * 5/9 + 3/7 * 5/9 7. 5/2 -( 3/2 + 4/5 ) 8. 7/8 + ( 1/8 + 1/9 ) 9. 9 * 5/6 + 5/6 10. 3/4 * 8/9 - 1/3 11. 7 * 5/49 + 3/14 12. 6 *( 1/2 + 2/3 ) 13. 8 * 4/5 + 8 * 11/5 14.
