上面要加上 ＋ － Ｘ ／ (所有符號都要用),
而左邊跟右邊的答案都是一樣?

✔ 最佳答案
所有符號都用:1 / 2 + 3 / 4 - 5 = 6 x 7 / 8 - 9

1*[(2-3)+(4-5)]=[(6-7)+(8-9)]

1*[(2-3)+(4-5)]=[(6-7)+(8-9)]=1*[-1+(4-5)]=[(6-7)+(8-9)]=1*(-1+-1)=[(6-7)+(8-9)]=1*(-1+-1)=[-1+(8-9)]=1*(-1+-1)=(-1+-1)=1*-2=-2=-2=-2

1 __ 2 __ 3 __ 4 __ 5 = 6 __ 7 __ 8 __ 9
(1-2 )*3 /(4-5) =6*(7-8) + 9
( -3)/(-1)= (-6)+9
3 =3
(1-2 )*3 /(4-5) =6*(7-8) + 9
( -3)/(-1)= (-6)+9
3 =3
