36 pieces divided by 4 will give you the total number of pies.
Subtract the two pies donated by the cafeteria, and you’ll have your answer.
You can also do it the other way around: The cafeteria donated 2 pies, times four piece each.
Subtract those pieces rom the total of 36 and divide that answer by 4.
Working it out two ways is always a good way to check your work and your understanding.
