Morphology

careless = care (transparent) = care + less

A direct negative formation: 'care' + '-less' means 'without care', which is straightforward for learners.

Etymology

The word careless comes from care and the ending -less, where care comes from an old English word for 'worry' or 'attention' and -less means 'without'. So careless literally means 'without care', which is why it describes someone who does not give enough attention and may make mistakes.
