(1)5 5 5 5 5 =2
(2)5 5 5 5 5 =3
(3)5 5 5 5 5 =4
(4)3 3 3 3 3 =10

1.(5+5+5-5)/5=2

2.(5+5)/5+5/5=3

3.5-(5+5-5)/5=4

4.3+3+3+3/3=10

(5+5)/5+5-5=2
(5*5-5-5)/5 =3
(5+5+5+5)/5 =4
3+3+3+3/3 =10

(1)【5 +5】/ 5 +5 -5 =2
(2)5 -【5/ 5 】-【5 /5】 =3
(3)5* 5/ 5 -【5/ 5】 =4
(4)3 +3 +3 +3 / 3 =10

(5+5)/5+5-5=2
(5*5-5-5)/5=3
5-5/5+5-5=4
3+3+3+3/3=10

(5/5*5+5)/5=2 5-(5+5+5)/5=2
5-5/5-5/5=3
5-5/5*(5/5)=4 (5+5+5+5)/5=20
3+3+3+3/3=10

1) 5-(5+5+5)除以5
2)5-(5除以5)-(5除以5)
3)5-(5除以5)+5-5
4)3除以3+3+3+3
