Well, let's think about this like a happy little math problem. If we add 2 + 4 + 6, we get 12. Then if we multiply that by 3, we get 36. Finally, if we add 1 to that, we get 37. If we multiply 37 by 3 again, we get 111. By subtracting 23, we get 88. And there you have it, a beautiful solution with just two operational signs!
The numbers are: -5 and 3
111 = 3*37
The three prime numbers which multiply to make 231 are 3 x 7 x 11.
There are 4 of them which are 2*3*3*3 = 54

To make 9, you can multiply 3 by 3 since 3 is a prime number. To make 10, you can multiply 2 by 5, both of which are prime numbers. Finally, to make 12, you can multiply 2 by 2 by 3, as 2 and 3 are prime numbers. By multiplying these prime numbers together, you can obtain the desired results of 9, 10, and 12.
