Evaulate: n
n-2 (expression should be in large brackets)
I got n! /n-2! 2! .
I know this is wrong but am not sure what to do next.
To evaluate the expression n - (n-2) in large brackets, it means you need to simplify the expression inside the brackets first.
Starting with the expression n - (n-2):
1. Distribute the negative sign inside the brackets:
n - n + 2
2. Combine like terms:
-n + n + 2
Since the -n and n terms cancel each other out, the simplified expression becomes:
2
Therefore, the evaluation of n - (n-2) is 2.
