Question

3．7．5＝1，2，3，⋯10怎么算？

Answer 1

3 - 7 + 5 ＝ 1
( 3 + 7 ) ÷ 5 ＝ 2
√( - ( 3 - 7 ) + 5 ) ＝ 3
√ ( 3 X 7 - 5) ＝ 4
3 + 7 - 5 ＝ 5
3 x ( 7 - 5) ＝ 6
√ - ( 3 - 7) + 5 ＝ 7
3! + 7 - 5 ＝ 8
- ( 3 - (7 + 5 ) ) ＝ 9
√ - (3 - 7) X 5 =1

Answer 2

3 - 7 + 5 = 1
3-(7 + 5)° = 2
- 3 °- 7 °+ 5 = 3
-( 3 + 7 )°+ 5 = 4
3 + 7 -5 = 5
3×( 7 - 5 )= 6
3°+7 - 5 °= 7
3 ! +(7 - 5 )= 8
- 3 + 7 + 5 = 9
(3+7 ) × 5 ° = 10
以上答案仅供参考

Answer 3

3 - 7 + 5 = 1
(3 + 7) / 5 = 2
min(3, 7, 5) = 3; 3 * floor(7 / 5) = 3; sqrt(-3 + 7 + 5) = 3
floor(3 * 7 / 5) = 4; min(-3 + 7, 5) = 4; sqrt(3 * 7 - 5) = 4; -ceil(3 / 7) + 5 = 4
3 + 7 - 5 = 5
3 * (7 - 5) = 6
max(3, 7, 5) = 7; sqrt(-3 + 7) + 5 = 7
min(3, 7) + 5 = 8; 3! + 7 - 5 = 8
-3 + 7 + 5 = 9
min 取最小值，max 取最大值， floor 向下取整， ceil 向上取整， sqrt 平方根

Answer 4

1加3加5加7加9 加⋯加29
=（1+29）x15÷2
=30x15÷2
=225

Answer 5

√(-3+7+5)=3
√(-3+7)+5=7
√(-3+7)×5=10
