Circular arrangement?
Say
FlowersBirthday FlowersSympathy FlowersIf items are arranged in a circle, in a certain order, then you would like to describe that order. However, one can travel two ways around a circle--clockwise and anti-clockwise. Think of placing a clock in the center of the circle of items. Usually mathematicians start numbering the items at the 12 o%26#039;clock position and then move around the circle as the hands on the clock move. This is a clockwise arrangement. If, after starting at the 12 o%26#039;clock position, you would start ordering the items by moving opposite of the hands on the clock, it would be anti-clockwise.acting resources
