Applying Subtraction to Drive the Robot Forward 13
```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
Modify the pre-placed blocks so that the robot will drive
forward 13 units. You can change one of the numbers or both
numbers as long as the difference between the two numbers
is equal to 13.*/
