Sure! Here’s a completed explanation:

Usually, when you add 99 to a number, you need to add 100 and then subtract 1.

Usually, when you add 100 to a number, you just increase that number by 100 without any other changes.

When you subtract 1 from a number, you simply decrease the value by 1.

Two simple steps can be easier than one difficult step because it breaks down the process, making it less complex and easier to manage. By adding 100 first and then subtracting 1, Emma can quickly perform the operation without having to calculate 99 directly, which might be more challenging.
