Here we give a few examples of the application of the overall “1” in the application of the problem-solving method. First, engineering problems a job, A alone to do for 10 days, B alone to take 12 days, C alone to take 15 days, A and C first to do 2 days, A left, C and 3 days later, B also alone Join in and ask
