3377算24

3377 (3+3/7)*7=24 (3+(3/7))*7=24 (3+3/7)*7=24 (3+(3/7))*7=24 (3/7+3)*7=24 ((3/7)+3)*7=24 (3/7+3)*7=24 ((3/7)+3)*7=24 (3+3/7)*7=24 (3+(3/7))*7=24 (3+3/7)*7=24 (3+(3/7))*7=24 (3/7+3)*7=24 ((3/7)+3)*7=24 (3/7+3)*7=24 ((3/7)+3)*7=2...

3377是个经典的算24题目,一般人要用120秒,因为涉及分数,有些人20秒就看出来了,比如我,具体算法是 7×(3+3/7) 另外3388也是比较经典的,算法是8/(3-3/8) 其他2个不难,(4-4/7)×7,4+4+8+8

(3+3)*(7-3)=24 ((3/3)+7)*3=24

这个还真没有

(3+3/7)x7 =(21/7+3/7)x7 =24/7x7 =24

(3+(3/7))*7 (3+(3/7))*7 ((3/7)+3)*7 ((3/7)+3)*7 (3+(3/7))*7 (3+(3/7))*7 ((3/7)+3)*7 ((3/7)+3)*7 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3)

(3+(3/7))*7 (3+(3/7))*7 ((3/7)+3)*7 ((3/7)+3)*7 (3+(3/7))*7 (3+(3/7))*7 ((3/7)+3)*7 ((3/7)+3)*7 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3) 7*(3+(3/7)) 7*((3/7)+3)

在3377这4个数中任意添加运算符号使结果等于24,共有4种算法。7×[﹙3÷7﹚+3]=7×[3/7+3]=7×24/7=24 7×[3+﹙3÷7﹚]=24 [﹙3÷7﹚+3]×7=24 [3+﹙3÷7﹚]×7=24

1: (3 + 3 ÷ 7) × 7 2: (3 + (3 ÷ 7)) × 7 3: (3 ÷ 7 + 3) × 7 4: ((3 ÷ 7) + 3) × 7 5: 7 × (3 + 3 ÷ 7) 6: 7 × (3 + (3 ÷ 7)) 7: 7 × (3 ÷ 7 + 3) 8: 7 × ((3 ÷ 7) + 3)

(3+3÷7)X7 =(24/7)X7 =24
