I am thinking of 3 different numbers from the set below.

When I add 2 of them together and then subtract the third one from the answer the result is a 2-digit number.

If I reverse the digits in this result it makes a number that is equal to half the product of my 3 numbers.

What 3 numbers do I have in mind?

Set of numbers : 23, 9, 6, 5, 1, 2, 4, 7, 18
