Re: Ok i'm still lost on this one
So, basically when you move the decimal to the right you subtract from the exponent?

What is the decimal goes to the left then what?

Re: Ok i'm still lost on this one
This is a basic arithmetic, just check it.
7.5x10^5 = 0.75x10^6
7.5x10^5 = 0.075x10^7
7.5x10^5 = 0.0075x10^8
7.5x10^5 = 75x10^4
