TIPS

  1. Addition of decimals is the process of finding the sum of two or more decimals.
  2. In the addition of decimals, arrange the decimals vertically according to their place values.
    Example:

  3. Subtraction of decimals is the process of finding the difference between two decimals.
  4. In the subtraction of decimals, arrange the decimals vertically according to their place values.
    Example:

    12.072 – 1.929 = 10.143
