Here's a simple set of instructions Shelia could write for her friend to find 10 more than any number:
1. Think of any number.
2. Add 10 to that number.
3. The result is 10 more than your original number.
For example:
- If you start with 5, add 10 to get 15.
- If you start with 23, add 10 to get 33.
- If you start with -7, add 10 to get 3.
