Arithmetic
One can be in situations where different mathematic operations must be performed in order to find a result. Four operations are known as basics in arithmetic: addition, subtraction, multiplication, and division. Some basic logic is also needed on certain problems to decide what operations are adequate.
We know 411 students went on a trip to the zoo. There were 9 buses filled but 6 students didn't fit, so they had to travel in cars. This information tells us that 411 - 6 = 405 students went on the buses.

There were 45 students in each bus
