Q5: ( ) + ( ) + ( ) + ( ) + ( ) = 30
This is what you have for the equation. The following are the numbers that you can use to fill in the brackets: 1, 3, 5, 7, 9, 11, 13 and 15. You can repeat the numbers if required. The resulting sum should be 30.
Answer: There is no mention if you can use a sign or not and thus the only possible way to get this is as follows: (15 – 9) + (13 – 7) + (7 – 1) + (9 – 1) + (13 – 9). If you solve inside the brackets, you will get the following equation 6 + 6 + 6 + 8 + 4. Adding all these numbers will give you 30.
