4.4+4.4乘12+13乘5.6的简算
快!

4.4+4.4乘12+13乘5.6的简算快!
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

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

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

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