Why I believe it is important to know how to calculate on your own, there can be cases where an item is on sale for x% off, maybe a store clerk doesnt include the discount, by knowing how to calculate what percentage was supposed to be taken off of the item you can tell the clerk!
of if you were to work in a store you would need to calculate discounts too even though we have the technology doesnt mean it always works or is right, its a good back up!
There are many instances where, you being the costumer or clerk should know what discounts you are getting,or giving, its just percaution for the future!
