Machine A (top) and B (bottom) shown on the board are individually programmed to perform specific math tasks. Each machine takes an input (orange circle) on the left and produce an output (pentagon) on the right. Watch the operation of each machine and answer the question prompt. Hint: it may help to write down the input-output of each machine. |
