  1. = · Every digit matches, so the numbers are equal.
  2. > · 4582 is bigger because its tens digit is larger.
  3. < · 10000 has one more digit than 9999. More digits means a bigger number.
  4. 6,120 · Thousands are tied at 6. In the hundreds place, 1 is bigger than 0, so 6,120 wins.
  5. 7028 · 7028 has the smallest hundreds digit, 0, so it is the smallest number.
  6. 3456, 3465, 3546 · Comparing the hundreds and tens digits shows 3456 is smallest and 3546 is largest.
  7. tens · After thousands and hundreds match, the tens digit is the next place value to check.
  8. He should start comparing from the thousands digit, not the tens · His answer is right this time, but the safe way is to start at the highest place value, the thousands digit, and move right only after a tie.
