可以試下自己做~ 式: 34-(26-12) =34-14 =20// 或用正負數: 34-(26-12) =34-26+12 =8+12 =20// 式: 35-(23-19) =35-4 =31// 或用正負數: 35-(23-19) =35-23+19 =12+19 =31//|||||最基本 34-(26-12) =34-14 先計括號內 =20 or 另一計算方法(較困難) 34-(26-12) =34-26+12 可先拆括號,然後把括號外的符號約,例:正負得負,負負得正 =20 答案同樣等於20|||||34-(26-12)=20 先計(26-12)~ =14 後計34-(14)~ =20 ps: ( )的數要先計~|||||34-(26-12) =34-14 =20 ==|||||34-(26-12) =34-14 =20|||||34-(26-12)=20|||||34-(26-12) =34-14 =20|||||34-(26-12) =34-14 =20|||||34-(26-12)=20 2007-02-03 11:20:09 補充: 35-(23-19)=31()|||||20 I hope I can help you
