9 + 3 = 6 × 2 .... The main concept of this research is as simple as the equation above; if the same answer is reached using two different methods; it means you can use either method to get your answer. The number 12 can be the answer of a 4 year old child of how much 9 plus 3, and it also can be the answer of what is the root square of 144. This study answers the questions, can an acrylic foam tape hold a certain load for 20 years? If so, how much tape should be used to hold that load? These questions usually answered using one way; which is hard to prove whether the answers are valid or not. This book answers the questions using different methods with explanation of each method used. At the end, I would like to add my voice to the great Ruth Benedict, who once said: "The trouble with life isn't that there is no answer, it's that there are so many answers".
