Let's understand the problem step by step:
- We have a small box that contains N biscuits. Here, N is a variable representing the number of biscuits in the small box.
- The medium box contains 10 more biscuits than the small box.
Since the small box has N biscuits, the medium box will have:
N + 10 biscuits
This is because if you have any number (N) and add 10 to it, you get N + 10.
Therefore, the expression for the number of biscuits in the medium box in terms of N is:
N + 10
