 ## Prefixes
 The SI system uses prefixes to represent multiples and submultiples of the base units. Here are some common prefixes used in the SI system:
 
-| Prefix | Symbol | Multiple       |
-| ------ | ------ | -------------- |
-| atto   | `a`    | $$ 10^{-18} $$ |
-| femto  | `f`    | $$ 10^{-15} $$ |
-| pico   | `p`    | $$ 10^{-12} $$ |
-| nano   | `n`    | $$ 10^{-9} $$  |
-| micro  | `μ`    | $$ 10^{-6} $$  |
-| milli  | `m`    | $$ 10^{-3} $$  |
-| centi  | `c`    | $$ 10^{-2} $$  |
-| deci   | `d`    | $$ 10^{-1} $$  |
-| Base   | -      | $$ 10^{0} $$   |
-| deca   | `da`   | $$ 10^{1} $$   |
-| hecto  | `h`    | $$ 10^{2} $$   |
-| kilo   | `k`    | $$ 10^{3} $$   |
-| mega   | `M`    | $$ 10^{6} $$   |
-| giga   | `G`    | $$ 10^{9} $$   |
-| tera   | `T`    | $$ 10^{12} $$  |
-| peta   | `P`    | $$ 10^{15} $$  |
-| exa    | `E`    | $$ 10^{18} $$  |
-| zetta  | `Z`    | $$ 10^{21} $$  |
