Write 0.007 in scientific notation

Step by step

The question

Question: write 0.007 in scientific notation.

1 What it looks like

Scientific notation is a number from 1 to under 10, times a power of 10.

2 Move the point

Moving the point 3 to the right made the number 1000 times bigger.

To make it the same again, we divide by 1000.

That is times 10⁻³.

So 0.007 is 7 × 10⁻³.

3 Check

Let's check: divide by 1000 moves the point 3 back to the left.

We get 0.007 again!

Let's look back.

First: what it looks like.

Then: move the point.

Last: check.
