Use a Robot for Addition and Subtraction
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.
```/* Code generated by RoboBlockly v2.0 */
/* Problem Statement:
Add driveDistance and traceColor blocks to calculate 8 + 9
- 3. The final position of the robot should give the
answer. 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.*/

// 8 + 9 - 3 = 14
robot.traceColor("#00FFFF", 3);
