6,757 + 7,667 = 568 + 14,686 =

67.56 + 386.76 = 7,576 + 6,768 = 3,275.86 + 69.67 = 3,576 + 74,968 = 58.96 + 96.78 = 26.87 + 98.69 = 57,768 + 12,686 = 7,685 + 36,769 =珠算减法练习

一、直减法练习

4,498 - 2,132 = 67,849 - 51,726 = 6,398 - 5,266 = 97,649 - 82,615 = 83,697 - 62,135 = 768.94 - 561.82 = 82,976 - 61,955 = 98.74 - 63.51 = 67,958 - 61,352 = 79,468 - 57,106 =二、破五减练习

6,857 - 2,413 = 758.66 - 424.48 = 5,768 - 1,324 = 7,586 - 3,142 =

8,756 - 4,312 = 55,863 - 12,432 = 865.76 - 441.32 = 86,755 - 42,312 = 65,875 - 42,431 = 458.67 - 14.23 =三、退十减练习

82,613 - 69,724 = 253.56 - 154.78 = 110.29 - 33.47 = 325.65 - 146.87 = 61,512 - 47,953 = 752.34 - 289.45 =

925.41 - 638.59 = 624.13 - 395.84 = 73,221 - 49,387 = 84,321 - 75,498 =

四、退十补五减练习

143.42 - 87.96 = 744.21 - 398.76 = 344.32 - 89.76 = 612.34 - 467.79 = 52,314 - 26,867 = 824.31 - 379.86 = 542.43 - 396.87 = 614.23 - 269.78 =
