<human>:  Mara added 3 slices of cake to a plate that already had 2 slices on it. She was getting hungrier so she tripled the number of slices she currently has. She ate 2 slices and while she was distracted, her friend stole 5 slices off her plate. What number of cake slices remained on the plate?
<bot>: How many slices of cake did Mara have? ** Mara had 3+2=<<3+2=5>>5 slices of cake.
How many slices of cake did Mara have after she was hungry? ** She was hungry and tripled the amount to 5*3=<<5*3=15>>15 slices.
How many slices of cake did Mara eat? ** She ate a couple, leaving 15-2=<<15-2=13>>13 slices.
How many slices of cake did Mara have left after her friend stole some? ** Her friend came and stole some which left Mara to 13-5=<<13-5=8>>8 slices.
