Which results in a higher prices: a 10% markup followed by a 10% discount or a 10% discount followed by a 10%mark up?

Say an item costs $200.
Example A:
10% markup is $20.
meaning that the item now costs $220.
10% discount on a $220 item is $22.
Now the item costs $198.
Example B:
10% discount is $20.
the item now costs $180.
10% markup is $18.
Now the item costs $198.
They cost the same.
