**Exponentiation**

If we allow the following symbol (^) to represent
exponentiation *(raising to a power)* and allow the following symbol (/) to
represent division, then we can write the values for the factors in the
earlier slide in the following ways.

(Note in particular the numbers in blue, which I will refer to later as the exponents.)

`1000 = 10^+3 = 1*10*10*10`

`100 = 10^+2 = 1*10*10`

`10 = 10^+1 = 1*10`

`1 = 10^+0 = 1`

`0.1 = 10^-1 = 1/10`

`0.01 = 10^-2 = 1/(10*10)`

`0.001 = 10^-3 = 1/(10*10*10)`

`0.0001 = 10^-4 = 1/(10*10*10*10)`

`0.00001 = 10^-5 = 1/(10*10*10*10*10)`

In the above notation, the term `10^+3
`means 10 raised to the third
power.
