四年級下冊數學混合運算？四則運算方法：一：在沒有括號的算式里，如果只含有同一級運算，要從左往右依次計算。二：含有兩級運算，要先算第二級運算，再算第一級運算。三：在有括號的算式里，要先算括號里的，再算括號外的。那么，四年級下冊數學混合運算？一起來了解一下吧。

擴展資料
1、一般情況下，四則運算的計算順序是：有括號時，先算括號里面的；只有同一級運算時，從左往右；含有兩級運算，先算乘除后算加減。
2、由于有的計算題具有它自身的特李拿征，這時運用運算定律，可以使計算過程簡單，同時又不容易出錯。
加法交換哪余搭律：a+b=b+a
乘法交換律：a×b=b×a
加法結合律：（a+b）+c=a+（b+c）
乘法結合毀沒律：（a×b）×c=a×(b×c)
