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? Assistant: 
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.
