Question

888×333-222×332的巧算？

Answer 1

888ⅹ333一222ⅹ332
=888ⅹ333一222ⅹ(333一1)
=888x333一222ⅹ333+222x1
=333x(888一222)+222
=333x666+222
=999x222+222
=222x(999+1)
=222ⅹ1000
=222000。

Answer 2

888×333-222x332
＝4x222x（332＋1）-222x332
＝4x222x332十4x222-222x332
＝（4-1）x222x332十4x222
＝3x222x332十4x222
＝996x222十4x222
＝（996十4）x222
＝1000x222
＝222000

Answer 3

888×333－222×332
＝888×333－222×（333－1）
＝888×333－222×333＋222×1
＝333×（888－222）＋222×1
＝666×333＋222×1
＝222×（999＋1）
＝222×1000
＝222000

Answer 4

888×333-222×332=222×4×333-222×332=222×（1332-332）=222×1000=222000
