{{Main|D'ni numerals}}
The D'ni counted in '''base-25''', i.e. they have 25 symbols per digit. But the system is actually simpler, because there are 5 basic shapes for digits from 0 to 5, then each of these is rotated on its side to represent a multiple of 5:

{| class="wikitable"
| style="text-align: center;" | <dni>0</dni>
| style="text-align: center;" | <dni>1</dni>
| style="text-align: center;" | <dni>2</dni>
| style="text-align: center;" | <dni>3</dni>
| style="text-align: center;" | <dni>4</dni>
|-
| style="text-align: center;" | 0
| style="text-align: center;" | 1
| style="text-align: center;" | 2
| style="text-align: center;" | 3
| style="text-align: center;" | 4
|-
| style="text-align: center;" | '''roon'''
| style="text-align: center;" | '''fah'''
| style="text-align: center;" | '''bree'''
| style="text-align: center;" | '''sen'''
| style="text-align: center;" | '''tor'''
|-
| 
| style="text-align: center;" | <dni>5</dni>
| style="text-align: center;" | <dni>)</dni>
| style="text-align: center;" | <dni>%</dni>
| style="text-align: center;" | <dni>[</dni>
|-
| 
| style="text-align: center;" | 5
| style="text-align: center;" | 10
| style="text-align: center;" | 15
| style="text-align: center;" | 20
|-
| 
| style="text-align: center;" | '''vaht'''
| style="text-align: center;" | '''nayvoo'''
| style="text-align: center;" | '''heebor'''
| style="text-align: center;" | '''rish'''
|}

When counting objects, numbers follow the noun they refer to, e.g. {{dni-text|kor|-tee||sen}} "three books".

The missing symbols are simply an overlap of two parts, e.g. 17 is 15 + 2. The names of the digits are a shortened form of the base ('''vaht''', '''nayvoo''', '''heebor''', '''rish''' → '''vah''', '''nay''', '''hee''', '''ri'') plus '''gah''' "and", plus the added number ('''fah''', '''bree''', '''sen''', '''tor''').

{| class="wikitable"

! bree

| <dni>{{huge|0 }}</dni> (0 '''roon''')
| <dni>{{huge|1 }}</dni> 1
| <dni>{{huge|2 }}</dni> 2
| <dni>{{huge|3 }}</dni> 3

|-
| <dni>{{huge|% }}</dni> 15 '''hee–gah'''
| <dni>{{huge|^ }}</dni> 16
| <dni>{{huge|& }}</dni> 17
| <dni>{{huge|* }}</dni> 18
| <dni>{{huge|( }}</dni> 19
|-
| <dni>{{huge|[ }}</dni> 20 '''ri–gah'''
| <dni>{{huge|] }}</dni> 21
| <dni>{{huge|\ }}</dni> 22
| <dni>{{huge|{ }}</dni> 23
| <dni>{{huge|} }}</dni> 24
|}

Example: {{dni-text|vahgahbree}}, {{dni-text|naygahtor}}, {{dni-text|rigahsen}} "seven, fourteen, twentythree"


In our base-10 system, each digit on the left is a power of ten, 10 times greater than the one in the right, e.g. the number 12,345 can be broken down as:

: 1&times;10<sup>4</sup> + 2&times;10<sup>3</sup> + 3&times;10<sup>2</sup> + 4&times;10 + 5&times;1 = 12,345

The D'ni numbering system works in the same way, except the base is not 10 but 25, so 12,345 in D'ni is a far bigger number:

: 1&times;25<sup>4</sup> + 2&times;25<sup>3</sup> + 3&times;25<sup>2</sup> + 4&times;25 + 5&times;1

: = 1&times;390,625 + 2&times;15,625 + 3&times;625 + 4&times;25 + 5&times;1

: = 423,855


We know the names of the first five powers of 25:

{| class="wikitable" style="text-align: center;"
| 25<sup>5</sup>
| 25<sup>4</sup>
| 25<sup>3</sup>
| 25<sup>2</sup>
| <dni>|</dni>
|-
| 9,765,625
| 390,625
| 15,625
| 625
| 25
|-
| <b>fah</b>–<b>blo</b>
| <b>fah</b>–<b>mel</b>
| <b>fah</b>–<b>lahn</b>
| <b>fah</b>–<b>rah</b>
| <b>fah</b>–<b>see</b>
|}

Each digit is written as the unit plus a suffix that denote the power, e.g.:

:4|5 is {{dni-text|tor}}-'''{{dni-text|-see}}''' {{dni-text|vaht}}

:12|21 is {{dni-text|naygahbree}}-'''{{dni-text|-see}}''' {{dni-text|rigahfah}}


When the value is 0, that digit is simply skipped.


Here is an example of a big number ( <dni>#^05!4</dni>&nbsp; = 133,206,529), broken down in its parts:

{| class="wikitable" style="text-align: right;"
| <dni>#^05!4</dni>
| DG05B4
|-
| naygahsen''blo''
| 13&middot;25<sup>5</sup>
|-
| heegahfah''mel''
| 16&middot;25<sup>4</sup>
|-
| 
| 0&middot;25<sup>3</sup>
|-
| vaht''rah''
| 5&middot;25<sup>2</sup>
|-
| naygahfah''see''
| 11&middot;25
|-
| tor
| 4
|}
