Strategies
This exercise is medium to get accuracy badges because the problem changes often. The speed badges are easy once you get over the fact that it changes on every problem because the timing tolerance is decent.
 * 1) The operations that are sometime required are multiplying or dividing by ten.
 * 2) Don't click too quick, you really need to reread the question to make sure you are answering the questions that is being asked.
 * 3) Most of the time the answers are written in correct order of their places, so it is relatively simple to rule out obviously wrong answers.
