數學問題,後日交,快d,thx~

4 4 4 4 = 2
4÷((4+4)÷4)=2
4x(4÷(4+4))=2
(4x4)÷(4+4)=2
4÷4+4÷4=2

4 4 4 4 = 4
4+((4-4)x4)=4
4+((4-4)÷4)=4
4-((4-4)x4)=4
4-((4-4)÷4)=4

4 4 4 4 = 6
4+((4+4)÷4)=6
(4+4)÷4+4=6

4 4 4 4 = 7
4+4-(4÷4)=7

4 4 4 4 = 9
4+4+(4÷4)=9

【1 (2 3 4) 56 7 】 8 = 8
【1x(2+3-4)+56+7】÷8=8

(1 2 3) 4 56 7 = 8
(1x(2+3)-4)x56÷7 = 8

12 3 4 5 = 8
12-3+4-5=8

如果仲有唔問, 可以email俾我, [email protected]

(4 x4) ÷ (4 +4) = 2
4 4 4 4 = 4
4 4 4 4 = 6
4+ 4- 4 ÷ 4 = 7
4 ÷ 4+ 4+ 4 = 9

(4+4)÷4+4=6

4÷4+4÷4=2

4x4÷4÷4=4

(4+4)÷4+4=6

4+4-4除1=7

4÷4+4+4=9
