Answer:

2*5*(3+7)+11=111

Explanation:

You can combine the numbers using operations like adding and multiplication.

I need to produce the 111. Since it's not an exact multiple of the other numbers, I make it as a sum. Thus 100+11=111. I used the 11.

Now I have to produce the 100 with the rest of the numbers.

I see a pair of numbers add up 10: 3+7=10

Thus I produce the other 10 by multiplying 2*5=10

Summarizing, the combination to make the result equal to 111 is

2*5*(3+7)+11=111
