Multiplication : Grouping Arrays
Problem Statement:
There is a multiplication problem on the board. Use the picture on the grid to solve the problem and answer the prompt.
/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double a;
double b;
CPlot plot;

a = randint(2, 23);
b = randint(2, 23);
// makes sure that none of the lines go past the grid
// continues creating random values for a and b until then
while(a * b > 529) {
  a = randint(2, 23);
  b = randint(2, 23);
}
