One example:
You go into a shop to buy some goods. The total price is 8.45 but you only have a 10.00 note. You give the note; How much change should you expect so that you can check you have receive d the right amount.
The amount of change to receive is the total price of 8.45 SUBTRACTED from 10.00, the value of the note.
Or, if you were the shop assistant, how much change should you give for goods at value when given a note of value 10.00?
You may say "but the till tells me," but the till has used subtraction of the value of goods sold from the value tendered to work out the change.
