1.火柴棒:
兩個算式都有錯誤 請問分別 至少要移動幾根火柴棒 才能將算式變正確
( V 2根 , I 1根 , + 2根 , = 2根 )
(1) VI + III = V
(2) XI + I = X
2.不同顏色六個球 放在 七個顏色不同的桌子
一次只能將一個球拿起來放到空桌子上 球一次最多移動兩個桌子
請問要幾次才能將所有的球放到同顏色的桌子上
● ● ● ● ● ●
┬ ┬ ┬ ┬ ┬ ┬ ┬
3.
有 1~9 的數字 印在 9 張紙上面
① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ 原本是這樣 ( 0找不到 )
不過 印數字的人不小心把 9個 數字都左右顛倒了
請問 至少幾張紙要重新印數字? (像0因為左右對稱 , 所以不用重印)
