Adam wants to eat some sliced apples. A large apple can be sliced into 5 pieces, and a small apple can be sliced into 3 pieces. Adam decides to slice 3 large and 5 small apples and then eats 15 slices. How many apple slices are left?
There are 3*5=<<3*5=15>>15 large apple slices.
There are 5*3=<<5*3=15>>15 small apple slices.
In total, there are 15+15=<<15+15=30>>30 apple slices.
After Adam eats 15 slices, there are 30-15=<<30-15=15>>15 apple slices remaining.
