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 5,650 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: 5,650
  • New Number: 5.650

Step 2

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

New Number: 5.650

There are 3 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 5.65 (Please notice any zeroes on the end have been removed)

b = 3

Now the whole thing:

5.65 x 103
