Perform a - b
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?". Refresh to try another problem. Look at Hint and/or Solution for example

/* Code generated by RoboBlockly v2.0 */
/* Problem Statement: 
    Add two numbers a - b on a number line. Move the robot tick
    mark along the number line, first to the red line, and then
    to the green line with the two preplaced driveDistance
    blocks. Refresh to try another problem.*/
