    1.口算下面各题

    (1)58+42= (2)87-45= (3)125×8=

    (4)50×12= (5)804÷4= (6)134+66=

    (7)1000-98= (8)720÷5= (9)0÷47=

    2.先填写下面各题的运算顺序,再计算出得数.

    (1)168+36-36+32=

    (2)153-5×14+83=

    (3)50×5÷50×5=

    3.判断:对的打“√”,错的打“×”

    (1)13×15与15×13表示的意义相同.( )

    (2)3000÷425÷8的计算结果一定小于3000÷(425×8)的计算结果.( )

    (3)两个因数的积是800,如果一个因数不变,另一个因数缩小20倍,那么积是40.( )

    (4)算式:“750÷25+35×2”所表示的意义是750除以25的商;加上35的2倍,和是多少?( )

    (5)24×25=6×4×25=6+100=106( )

    4.用简便方法计算:
