0×5、0×0、0+5三個(gè)算式的得數(shù)


  1. A.
    相等
  2. B.
    不都相等
  3. C.
    都不相等
B
分析：根據(jù)題意，分別計(jì)算出0×5、0×0、0+5三個(gè)算式的結(jié)果，然后再進(jìn)一步選擇即可．
解答：根據(jù)題意可得：
0×5=0；
0×0=0；
0+5=5；
所以，0×5=0×0，但不等于0+5，也就是這三個(gè)算式的得數(shù)不都相等．
故選：B．
點(diǎn)評(píng)：本題主要考查有關(guān)0的乘法和加法，0乘任何數(shù)都得0，而任何數(shù)加0還得原數(shù)．
