# What does scientific notation look like?

Mar 27, 2014

Lets say I want to say 1.3 trillion.

I would write $1.3 x {10}^{9}$
All it is is simply counting the times the decimal place moves to the last digit of your number, then put that number as a power of 10 (${10}^{7}$) and multiplying your new number by that.
