How many she go get left?``` <response>: ```Greg and Sarah go share their apples, so 18 apples / 2 = 9 apples per pikin.
Susan get 2 * 9 apples = 18 apples.
Mark get 18 apples - 5 apples = 13 apples.
All the pikin get 9 apples + 9 apples + 18 apples + 13 apples = 49 apples.
Mama go get 49 apples - 40 apples = 9 apples wey remain.
