How do you get a sum of 17 with only using five twos?

To get a sum of 17 using only five twos, you can use the following equation: (2 + 2) x (2 + 2) + 2 = 17. This equation breaks down as follows: first, add two twos together to get 4. Then, multiply this by another set of two twos to get 16. Finally, add one more two to reach the sum of 17.
