Scientific Notation
We can write numbers as the product of a power of 10 and a number greater than 1 but less than 10 (9.9999…. to be exact). Standard notation is the stuff that we are normally used to.
Examples: `4.58 × 10^4=45,800`
`(3.0 × 10^5)(4.1 × 10^(-3))=(3.0⋅4.1 ) * (10^5 × 10^(-3))=12.3 × 10^2=1.23 × 10^3`
`(2.5 × 10^(-7))/(5.0 × 10^6) = (2.5/5.0) * (10^(-7)/10^6) = 0.5 × 10^(-13) = 5.0 × 10^(-14)`
