    Sally found 73 seashells on the beach, she gave Mary some of her seashells. She has 10 left. How many did she give to Mary?

    Let the number of seashells Sally gave away as g. We're given:
    73 - g = 10

    To solve this equation for g, we type it in our search engine and we get:
    g = 63
