Use BEDMAS.

Brackets
Exponents
Division
Multiplication
Addition
Subtraction.

Explanation:

Using BEDMAS we get:

Step 1: Exponents first (there are no brackets).

22 div 11 times 9 - color(red)(3^2)

=22 div 11 times 9 - color(red)9

Step 2: Divison next.

color (red)(22 div 11) times 9 - 9
=color (red)(2) times 9 - 9

Step 3: Multiplication next.

color(red)(2 times 9) - 9

=color(red)18- 9

Step 4: Subtraction next (there are no terms that need addition).

color (red)18-9

=color(red)9
