(5+3(3))+3=30 That was easy. I'm not adding any extra plus signs, it says numbers can be used multiple times and the [b]()[/b] are bold meaning they are usable. As an Edit because several people below couldn't do basic Algebra: (5+3(3))+3=0 \/ (8(3))+3=0 \/ (27)+3=0 Answer: 27+3=30 I did my own order of operations btw, the given problem does not state the basic rule of operations as a necessity. I used the provided tools, developed a method, and gave a solution. I'm sorry crucify me I broke the rules of mathematics by coming up with my own solution. Because yah now... -blam!-in rules man...
