Bar codes are numbers on something your buying in the shop.

In enrichment we did a challenge on doing 5 bar codes and we have to work out the last digit in the code.
         When you do one you add the seven on the top and you have your answer and then you add the ones on the bottom row and multiply your answer by three and only take the last digit number in your answers and  ask the person that is holding the code and tell them your answer.
                                            example down below.
