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
=(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
