Torn Apart
  • The numbers thirty and twentyfive separated by jagged line
    Notice the 4-digit number above. All of the digits are different and if you tear 3025 down the middle and take the two 2-digit numbers formed by this separation, an interesting oddity occurs. The sum of 30 and 25 is 55 and the square 55 is the orginal number, 3025. Find another 4-digit number that shares this same oddity.
