### A good answer might be:

Base five Representation | Base ten Representation
--- | ---
0 | 0
1 | 1
2 | 2
3 | 3
4 | 4
10 | 5

# Changing Representations

You may wish to change the representation of a number from base 5 notation into base 10 notation. Do this by symbol replacement. Change the base 5 symbols into the base 10 symbol equivalents. Then do the arithmetic.

> 4215 | = | `4 × 1052 + 2 × 1051 + 1 × 1050`
> the number repd in base 10 | = | `4 × 5102 + 2 × 5101 + 1 × 5100`
> the number repd in base 10 | = | `4 × 25 + 2 × 5 + 1 × 1`
> the number repd in base 10 | = | `100 + 10 + 1 = 11110`

The above process is often called "converting a number from base 5 to base 10". But in fact, the number is not being converted, its representation is being converted. The characters "421 (base five)" and "111 (base ten)" represent the same number.
