 ## Cosmetic Underscores
 
 You can add underscores to your numeric literals to make them more readable.
-```pluto showLineNumbers title="Example Code"
+```pluto
 local n = 10_000_000
-assert(n == 10000000)
+print(n) --> 10000000
 ```
 These underscores are ignored by the compiler, so they are purely cosmetic.
 
-## Binary Integers
+## Binary & Octal Numerals
 
 Similar to how Lua allows you to input numbers in hexadecimal:
-```pluto showLineNumbers title="Example Code"
-local n = 0x420
-assert(n == 1056)
+```pluto
+local n = 0x2A
+print(n) --> 42
 ```
-Pluto allows you to input numbers in binary as well:
-```pluto showLineNumbers title="Example Code"
-local n = 0b1000101
-assert(n == 69)
+Pluto allows you to input numbers in binary and octal as well:
+```pluto
+local n = 0b101010
+print(n) --> 42
+```
+```pluto
+local n = 0o52
+print(n) --> 42
 ```
