Applying Addition and Subtraction to Drive a Robot Forward: 2 + 9 - 16
Problem Statement:

Modify the driveDistance blocks to calculate 2 + 9 - 16. The first block should drive the robot to the light blue line, the second to the red line, and the final block should take it to the dark blue line.

```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
Modify the pre-placed blocks and add in more drive-Forward
and/or Drive-Backward blocks to solve the problem 8 + 9 - 3.*/
