10.3×99+10.3的简便算法
问题描述:
10.3×99+10.3的简便算法
答
原式=10.3×(99+1)=1030
答
=10.3*(100-1)+10.3
=10.3*100-10.3*1+10.3
=1030-10.3+10.3
=1030
答
10.3*99+10.3
=10.3*99+10.3*1
=10.3*(99+1)
=10.3*100
=1030
答
10.3*(99+1)=10.3*100=1030
答
10.3x(99+1)=10.3x100=1030
答
10。3×(99+1)=1030
答
10.3×99+10.3
=10.3×(99+1)
=10.3×100
=1030.
答
10.3×99+10.3
=10.3×(100-1)+10.3
=1030-10.3+10.3
=1030
