  • Lesson 1-8

The Basics
  • When you multiply by 10, 100, or 1,000, you can
    move the decimal point to the right.
  • The number of decimal places you move is the same
    as the number of zeroes you are multiplying by.
  • When you divide by 10, 100, or 1,000, you can
    move the decimal point to the left. Move the
    decimal point once for each zero you are dividing
    by.
