elementary math

i use arduino permit our students opportunity see math in action asking them edit code power stepper on hacked scanner.  if successful, plan build robot navigate course based upon equations.  these elementary students numbers must no greater 3 digits or less little ones.  the code failed attempt achieve goal.  as may guess, not programmer wonder if there way assign value variable within "range" , students can use appropriate operator adjust there.  hope makes sense?

#include <stepper.h>

#define motorstep 400
#define motorpin1 8
#define motorpin2 9
#define motorpin3 10
#define motorpin4 11
#define turn 12

int count;

stepper mystepper(motorstep, motorpin1,motorpin2,motorpin3,motorpin4);

void setup() {
 mystepper.setspeed(40);
 serial.begin(9600);
 count = 1;
 digitalwrite (turn, high);
}

void loop () {
 if (count) {
   count--;
   serial.println ("forward");
   mystepper.step(1500+1400);
   delay(500);
   
   serial.println ("backward");
   mystepper.step(-1500-1400);
   delay(500);
 }
}

hi frank, not clear me want do, can clarify?
