Decimal Operations

Learn to add, subtract, multiply and divide with decimals

Adding Decimals

Steps:


  1. Write down the numbers, one under the other, with the decimal lined up.
  2. Put in zeros so the number have the same lenght.
  3. Then add using column addition, remembering to put the decimal point in the answer.

Subtracting Decimals

Steps:


  1. Write down the two numbers, one under the other, with the decimal point lined up.
  2. Add zeros so the numbers have the same lenght.
  3. Then subtract normally, remembering to put the decimal point in the answer.

Multiplying Decimals

Steps:


  1. Multiply normally,ignoring the decimal points.
  2. Then put the decimal point in the answer-it will have as many decimal places as two original numbers combined.

Dividing Decimals

Steps:


  1. Use division or long division (ignoring the decimal point).
  2. Then put the decimal point in the same spot as the dividend (the number being divided).
