Answer:
The result is 19
Step-by-step explanation:

Step 1: Parenthesizing (5-2)=3

Step 2: Exponentiation 

Step 3: Multiplication and division 3x4=12 and 6/3=2

Step 4: Addition and subtraction 9+12=21, and 21-2=19
21-2
19
The operations are ordered from highest to lowest in the order:
1. Parenthesizing,
2. Factorial,
3. Exponentiation,
4. Multiplication and division,
5. Addition and subtraction.
Hope this helps!
You could put,
19
+ 6
———
25
Then write,
19+6=25
