一、直接写出得数:
3.7 + 8.4 = 12.1
0.58 + 3.2 = 3.78
6 - 3.3 = 2.7
5.4 - 2.8 = 2.6
25 × 16 = 400
6.68 - 2.5 = 4.18
6.38 + 8.62 = 15
3.92 - 0.2 = 3.72
0.225 × 10 = 2.25
100 × 2.03 = 203
6.2 ÷ 10 = 0.62
123 ÷ 100 = 1.23
0.025 × 100 = 2.5
13 - 2.3 - 3.7 = 6
4 × 28 × 2
5 = 2800
36 ÷ 2.55 = 14.12
2.8 + 58 × 0 = 2.8
5.5 + 4.52 + 4.5 = 14.52
100 × 3 ÷ 100 × 3 = 3
二、竖式计算并验算:
12.65 + 7.5 = 20.15 (验算正确)
83.6 - 4.35 = 79.25 (验算正确)
三、计算,有些能简便的要简便计算:
99 × 85 + 855.63 + 8.8 + 4.37 + 1.236 × 19 - 9 × 36 = 8,422.72
可简便计算为:99 × 85 + 855.63 + 8.8 + 4.37 - 9 × 36 + 1.236 × 19 = 8,422.72)
55 × 101 = 5,555

1.计算题练:
2.38-2.4+
3.62 = 3.6
125×24 = 3000
75×55+75×45 = 7500
27.5-6.8-3.2 = 17.5
55.83-(3.2+5.83) = 46.2
29×125×8 =
5600÷25÷4 = 56
250÷8×4 = 125
58+(124-24×3)= 62
32.3-(5.02+2.03×10)= 10.3 32×18+(32.6+18.09)= 725.69
2.直接写出得数:
3.7+7.3=11
0.56+3.4=3.96
6-3.22=2.78
5.4-4.5=0.9
25×28=700
