David has 12 pieces candy and Heather has 13 pieces of candy.If their baby brother eats 4 pieces of their cand how many pieces of candy do the children have left

12 +13 = 26 and since the baby brother ate 4 pieces of candy  26 - 4 = 22 pieces of candy left Maybe

The children would either have 8 pieces of candy, 9 pieces of candy or 21 pieces of candy.
