3*(8-4+2)=18
2*(8+4-3)=18
3*8-2-4=18
3*4+8-2=18
2*3+4+8=18
。。。。不一一列舉了,見諒

分數的加減乘除的演算法和規律 急急
分數加法為 同分母時,只把分子相加,分母不變。異分母時把分母通分為同分母,分母擴大或縮小多少倍,分子也要擴大或縮小多少倍。分數減法 同分子時只把分子相減,分母不變。異分母時6先把分母同分,分母擴大或縮小多少倍分子也擴大或縮小多少倍。分數乘法 分子與分子相乘,分母與分母相乘。分數除法 被除數不變,除以...
奇偶數的加減乘除的公式是啥
墨汁諾 當兩個數進行加減乘除運算的結果為大於1的整du數時,有以下規律 奇數與奇數相加減為偶數,偶數與偶數相加減為偶數,奇數與偶數相加減為奇數 奇數與奇數相乘為奇數,偶數與偶數相乘為偶數,奇數與偶數相乘為偶數 奇數與奇數相除為奇數,偶數與偶數相除不確定 如4 2 2為偶數,6 2 3為奇數 偶數除以...
