to the green line with the two preplaced driveDistance
blocks. Refresh to try another problem.*/

Problem Statement:

An a - b problem is given on the grid. Modify the preplaced blocks to drive forward a units and then backward b units. Then, use the robot's final position to answer: "what's a - b?". Click New Problem for new problems. Look at Hint and/or Solution for example
