This is a great method
I call it dot traveling
if you have 3.025 and 100 has 2 zeros you move your dot by 2 spaces so 302.5
next
if you have 10^5 you will need to look only at the five (note: this is ONLY on the number 10)
so we are going to move 3.025 by 5 spaces
notice how it doesnt have enough space? Add zeros!
So here 3.025 * 10^5 = 302500!
Hope I helped
