Scientific Notation
First, when we say scientific notation,
<Previous screen remains. Text appears
as follows below previous>
5.47 × 106
we mean numbers written like this.
<Previous screen remains. Text color of
5.47 changes to red. Additionally, a red
arrow appears from 5.47and points to new
text as follows>
5.47 × 106
They have two parts to them: a coefficient,
which is a number between 1 and 10
written in front,
1 < Coefficient < 10
<Previous screen remains, but the
1 < Coefficient < 10 text and arrow
disappear. Red color font also removed
from 5.47. Now, text color of 106 changes
to blue, and a blue arrow appears from
