递等式计算 (3.6+8.4)÷0.25
=(3.6+8.4)*1/4
=3.6*1/4+8.4*1/4
=0.9+2.1
=3
2.3x8.37+16.3x2.3
=2.3*(8.37+16.3)
=2.3*24.67
=(2+0.3)*24.67
=2*24.67+0.3*24.67
=49.34+7.401
=56.744
25×23×8
=25×8×23
=200×23
=4600
看
=37×25+75×(23+14)
=37x25+75×37
=37x(25+75)
=37×100
=3700
尉师冠心: 解: 128*125*25*625*13 =(8*4*4)*125*25*(25*25)*13 =(8*125)(4*25)(4*25)*25*13 =1000*100*100*325 =3250000000 =3.25*10^9
