Problem number 7. Pablo put 10 toy cars on this racetrack. How many cars are in the tunnel?  So on this racetrack, there's a total of 10 cars. We can see some of them, and the rest are in the tunnel.  Let's count the cars that we can see. 1, 2, 3, 4. There are 4 cars that we can see, and there is a total of 10 cars.  So we need to find the number that we need to add to 4 to make 10. 4 plus 6 makes 10.  So there are 6 cars in the tunnel.  We can also solve this by subtraction. There are 10 cars total. We can see 4 of them.  So there are 10 minus 4, or 6 cars that we can't see, which are in the tunnel. Answer is B.

Video Summary

Pablo placed a total of 10 toy cars on a racetrack. Visible are 4 cars, implying that the remaining 6 cars are in the tunnel. This is determined by calculating the difference between the total number of cars and the number visible: 10 minus 4 equals 6. Thus, 6 cars are in the tunnel.
