  1. thousands · Thousands is right: 1000 adds exactly one thousand. A carry can also change higher places.
  2. 4,472 · 1000 more changes the thousands digit from 3 to 4, so 3,472 becomes 4,472.
  3. 5,562 · 1000 more changes the thousands digit from 4 to 5, so 4,562 becomes 5,562.
  4. True · A 1000 jump changes the thousands place. A carry or borrow can change higher places too, while the hundreds, tens, and ones stay the same.
  5. True · Eli is right: 4 thousands become 5 thousands and the rest stay put.
  6. The thousands digit · 1000 belongs in the thousands place. A carry or borrow may also change higher places.
  7. 10,526 · 10,526 is right because 9 thousands plus 1 thousand makes 10 thousands.
  8. 27740 · 26,740 plus 1000 is 27,740.
  9. He changed the ones digit instead of the thousands digit · 1000 more changes the thousands digit. 12,345 should become 13,345, not 12,346.
  10. False · Suki is wrong: 9,899 + 1000 = 10,899, and the hundreds, tens and ones stay 8, 9 and 9.
