4.4+4.4*12+13*5.6怎 么简便计算?

=4.4*13+5.6*13
=(4.4+5.6)*13
=130

4.4+4.4*12+13*5.6
=4.4+4.4*12+12*5.6+1*5.6
=10*12*10
=130

学生惜诺,你好:
4.4+4.4*12+13*5.6
=4.4×(1+12)+13×5.6
=4.4×13+13×5.6
=13×(4.4+5.6)
=13×10
=130

4.4+4.4*12+13*5.6
=4.4*(1+12)+13*5.6
=13*4.4+13*5.6
=13*(4.4+5.6)
=13*10
=130

4.4+4.4*12+13*5.6
=4.4*(12+1)+13*5.6
=4.4*13+13*5.6
=(4.4+5.6)*13
=10*13
=130

4.4+4.4*12+13*5.6=4.4(1+12)+13*5.6=4.4X13+13*5.6=13X(4.4+5.6)=13X10=130
