18.8乘以5.8加7.2乘以4.2加11.6乘以4.218.8乘以5.8加7.2乘以4.2加11.6乘以4.218.8乘以5.8加7.2乘以4.2加11.6乘以4.218.8乘以5.8加7.2乘以4

18.8乘以5.8加7.2乘以4.2加11.6乘以4.2
18.8乘以5.8加7.2乘以4.2加11.6乘以4.2

18.8乘以5.8加7.2乘以4.2加11.6乘以4.2
18.8乘以5.8加7.2乘以4.2加11.6乘以4.2
=18.8*5.8+4.2*(7.2+11.6)
=18.8*5.8+18.8*4.2
=18.8*(5.8+4.2)
=18.8*10
=188

原式=18.8*5.8+18.8*4.2=18.8*10=188

18.8×5.8+7.2×4.2+11.6×4.2 有没有括号啊??(18.8×5.8)+(7.2×4.2)+(11.6×4.2)

答案有很多中的,呵呵
