五年级下册数学口算题带答案

五年级数学口算题,要答案,越多越好,急用。

如下:

1740=680, 100-63=37, 3.2+1.68=4.88, 2.80.4= 1.12

14-7.4=6.6, 1.920.04=48, 0.32500=160, 0.65+4.35= 5

10-5.4=4.6, 420=0.2, 3.5200=700, 1.5-0.06=1.44

0.7515=0.05, 0.40.8=0.32, 40.25=1, 0.36+1.54=2

1.0199=99.99, 42035=12, 2512=300, 1350.5=270

3/4 + 1/4 =1, 2 + 4/9 =22/9, 3 - 2/3 =7/3, 3/4 - 1/2= 1/4

1/6 + 1/2 -1/6 =1/2, 7.5-(2.5+3.8)=1.2, 7/8 + 3/8 =5/4

3/10 +1/5 =1/2, 4/5 - 7/10 =1/10, 2 - 1/6 -1/3 =1.5

0.5117=0.03, 32.8+19=51.8, 5.21.3=4, 1.60.4= 0.64

4.90.7=3.43, 15=0.2, 612=0.5, 0.87-0.49=0.38

口算:一边心算一边口说地运算。口算就是用脑计算,用口头叙述来记忆当时的结果。这种方法用于速算,常练有助于智力的提高。也成为如今的主流的计算方法。也叫“心算”。

数学教学方法之一。一种只凭思维及语言活动不借任何工具的计算方法。它能培养学生快速的计算,发展学生的注意、记忆和思维能力。口算熟练后有助于笔算,且便于在日常生活中应用。

口算:一边心算一边口说地运算。口算就是用脑计算,用口头叙述来记忆当时的结果。这种方法用于速算,常练有助于智力的提高。也成为如今的主流的计算方法。也叫“心算”。

数学教学方法之一,一种只凭思维及语言活动不借任何工具的计算方法。它能培养学生快速的计算,发展学生的注意、记忆和思维能力。口算熟练后有助于笔算,且便于在日常生活中应用。
