1-0.8= 15-2.6= 30.5÷1000=
24×5= 2.3-0.8-0.2= 20-20÷5=
4.7-2.9= 2.3×10=
综合算式:( )
0.7+2.61.9+2.6
2.8+3.63.6+2.8
4-3.5+0.54-(3.5+0.5)

4.8+5.02= 20-3.5= 5.8÷10= 1÷5=
93÷1000= 10+3.8= 12.5×8= 6.7+4.3=
7.2-2= 3.25×10= 120÷100= 2.99×3.02=
0.82= 0.89-0.8= 3.6+0.04= 2.5×4×0=
因为:26×2=52 26×4=52×2=104 26×8=104×2=208
所以:26×13=208+104+26=338
你能用乘法分配律来解释上面的计算过程吗?填一填
26×13=26×(8++)
=26×8+26×+26×
=208+104+26
=338
