73-25=48;58-39=19;54-36=18;16+37=53;23+38=61;48+26=74;40-13=27;17+34=51;43-29=14.

77-46+32 65-38+26 79+19-56 56+74-26 = = = = = = = = 58-36+27 84-27+16= 4+27-16 = = = = = = 93+23+94 69-(39-23) 99+(25-24) = = = = = = 77-76+32 61-38+26 79+19-16 16+77-26 = = = = = = = = 18-36+27 87-27+16 30+(23-29) = = = = = ...

36+12=48 24+31=55 51+23=74 35+23=58 34+26=60 22+39=61 56+26=82 35+25=60 44+27=71 46+18=64 45+49=94 17+48=65 26+54=80 29+65=94 73+15=88

58×36 +61×36用简便算法 =36×(58+61) =36×119 =4284

42×36+ 36×58 =36x(42+58) =36x100 =3600 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

36×42+36×58 =36×(42+58) =36×100 =3600
