8.00*25.00*23.00=? (Zeros not necessary; needed to fill character requirement).
30 x 30 = 900 too low
40 x 40 =1600 too high - so the answer lies somewhere between
30 x 31 (too low) 39 x 40 = too high
31 and 37 are the only primes between those numbers and that is her pin 3137
You have to square it all up then add it up if you want you can use the calculator
