Your trial build is not sufficiently advanced, you’ll need more than an adder-subtractor. The bar for trial builds is at or above the level of a 4 Bit ALU. Please respond with a new build if/when you decide on one.
This application has been accepted! Whenever both you and a staff member are free, feel free to ask them for a trial. You are able to try again after failing and waiting 24 hours. It is always recommended to do a practice trial with another member before starting your real one and to practice the questions found at ORE Binary Quiz to help prepare for some of the trial questions.
