Write the number as (a times 10^n), where (1 le |a| < 10)
Move the decimal point until the coefficient (a) is between 1 and 10
Count how many places you moved the decimal point
Use a positive exponent (n) if you moved the decimal point left
Use a negative exponent (n) if you moved the decimal point right
Keep the sign of the original number in (a)
Example: (4500 = 4.5 times 10^3)
Example: (0.0067 = 6.7 times 10^{-3})
For converting from scientific notation to standard form: multiply (a) by (10^n)
If (n>0), move the decimal point right (n) places
If (n<0), move the decimal point left (|n|) places
Example: (3.2 times 10^5 = 320000)
Example: (7.5 times 10^{-4} = 0.00075)
