() × () = () () = () × () () () fill in 1 ~ 9 numbers, which cannot be repeated
29x6=174=3x58
Please fill in the following () with 1 ~ 9 digits. It can't be repeated!
（ ）+（ ）=（ ）
（ ）-（ ）=（ ）
（ ）=（ ）-（ ）
Please fill it in. Thank you!
No answer
Proof: from 1 to 9 equals (1 + 9) * 9 / 2 = 45
If the above three equations hold, that is, left = right, and left + right = 45, then left = right = 45 / 2 is not an integer
So there is no answer
Please fill in the following () with 1 ~ 9 numbers, which can't be repeated!
（ ）+（ ）=（ ）
（ ）-（ ）=（ ）
（ ）=（ ）-（ ）
There is no solution. Because () + () = () + () = () + () = () + () = () there is no solution
It's 24:5.8.9.6
I want to write a tree diagram
(8+5-9)*6=24
(3,3,8,8) (3,3,7,7) is 24 points,
8/(3-8/3) (3+3/7)*7
1、 4,6,7,9
2、4,4,10,10
3、1,7,13,13
4、5,10 ,10 ,11
5、2 ,6 ,9 ,9
6、2 ,7 ,10,10
7、1 ,3,4 ,6
8、1 ,4 ,5 ,6
6 ÷ 4 ×(7 + 9)=246 × (9 + 7) ÷ 4=24（10 × 10-4）÷ 4=24(13 × 13 - 1) ÷ 7=24(10 + 10 × 11) ÷ 5=24(2 + 6 ÷ 9) × 9=242 × (9 - 6 + 9)=242 × (7 + 10) - 10=24(10 - 7) × (10 - 2)=246 ÷ (1 - 3 ...
For math, count 24
Calculate 24 points; if power operation is allowed, can you list different formulas that meet the requirements?
3,4,5,2
11,2,10,5
5 ^ 2-4 + 3 (or 4 ^ 2 + 5 + 3)
11 + 10 + 5-2 (or 11 * 2 + 10 / 5)
Math 24
Use 11, 12, 3 and 14 to calculate 24 points
11.12.13.14 24 points
14-13+12+11= 1+12+11=24
3, - 5, - 10, - 13, 24
3 times - 13 equals - 39
Minus 10 from - 5 equals - 15
15 minus 39 equals 24
3、7、-5、-13
（-13）×（-5）=65
65+7=72
72÷3=24
