Use BEDMAS.

Brackets
Exponents
Division
Multiplication
Addition
Subtraction.

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#
