# My route or quantity guide

Fictional quantity card set: Label counts around four hundred. First card states 390 labels; second card states 400 labels; third card states 410 labels. These are stated counts of the same kind of label, not observed stocks, money, distances or prices. An extra number-line guide states 390,400,410,420 in this order, with equal ten-label intervals. The task is to represent, compare or order these stated quantities and give a checking reason.

Make a useful quantity guide. Keep the whole quantity and the value of each digit clear.
