using random numbers in random numbers, you can get a good random number.

random 1: rnd(1,10);
random 2: rnd(rnd(1,10),rnd(1,10));
random 3: rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10)));
random 4: rnd(rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10))),rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10))));
random 5: rnd(rnd(rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10))),rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10)))),rnd(rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10))),rnd(rnd(rnd(1,10),rnd(1,10)),rnd(rnd(1,10),rnd(1,10)))));
