Problem: Sarah had 4 candies. After her friend gave her some more, she had a total of 10 candies. How many candies did her friend give her?

Gemma 2B:

    To determine how many candies Sarah's friend gave her, we need to find the difference between the total number of candies Sarah had after receiving the additional candies and the number of candies she originally had.

    Sarah originally had 4 candies.
    After receiving more candies, she had a total of 10 candies.
