How to explain it to your child

Column by column — ones, tens, hundreds — and carry when a column passes 9.

  1. Write the numbers in columns, ones under ones. — 234 + 198
  2. Add the ones. More than 9? Write the ones digit, carry 1. — 4 + 8 = 12 → write 2, carry 1
  3. Add the tens plus the carry. — 3 + 9 + 1 = 13 → write 3, carry 1
  4. Add the hundreds plus the carry. — 2 + 1 + 1 = 4

Example: 234 + 198 = 432.
