The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 66,200 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

  • Original Number: 66,200
  • New Number: 6.6200

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 6.6200
