Have 6 number of trucks and 2 number of cars.

What is the difference between the number of cars and trucks?

To find the difference between the number of cars and trucks, you need to subtract the number of cars from the number of trucks.

In this case, you have 6 trucks and 2 cars. So the difference is:

6 trucks - 2 cars = 4

Therefore, the difference between the number of cars and trucks is 4.
