Understanding Decimal Multiplication

Decimal multiplication is similar to multiplying whole numbers, but you need to account for the decimal point. Here's a simple breakdown:

  • Ignore the decimal points: Multiply the numbers as if they were whole numbers.
  • Count decimal places: Count the total number of decimal places in both numbers you are multiplying.
  • Place the decimal point: In the product, count from right to left the same number of places you counted in the previous step and place the decimal point there.

Example: Multiply 2.5 and 12.

  • Multiply 25 and 12 as whole numbers: 25 x 12 = 300.
  • Count decimal places: 2.5 has one decimal place, and 12 has zero, totaling one decimal place.
  • Place the decimal point: Starting from the right of 300, move one place to the left to get 30.0.

Thus, 2.5 x 12 = 30. This calculator helps you perform these calculations quickly and visualize the multiplication process.
