HeLiiLii

Full name: He+Li-I+Li-I (2+3-53+3-53)
==About HeLiiLii==
HeLiiLii (pronounced heh-lee-lee) is an esoteric programming language designed by User:Magnogen in 2021, although the idea behind it was devised way back in 2011, but I never got around to making it into a real thing.
HeLiiLii is based around using the chemical symbols of elements on the periodic table and performing mathematical-like rules on them to create words.
==Mathematical operations on elements==
All elements are defined by their atomic number (it's protons/electrons), Hydrogen (H) being 1, Helium being 2, etc.
This means that numbers don't work as you might think:
 8 does NOT equal 8
 8 -> oxygen = "o"
Also, negative numbers are treated as capitals:
 -8 -> OXYGEN = "O"
Because of this, the mathematical operations might seem a bit unintuitive, especially subtraction, so you can find them listed below
===Addition===
When adding two elements, you always join them together - think of them like strings.
 8+92+7 -> fluorine+uranium+nitrogen = "f"+"u"+"n" = "fun"
That might be an overstatement... But you get my point.
===Subtraction===
Subtraction works a little differently; if the first element contains the second, it removes the second from the first.
 22-53 -> titanium-iodine = "ti"-"i" = "t"
This can be used to obtain new characters that wouldn't be available otherwise, such as the letter "t" in the example.
Subtracting negative elements can be a little finicky, as they are interpreted as capitalization.
 -22-53 -> TITANIUM-iodine = "TI"-"i"
As you can see, "TI" doesn't contain "i" (it's case-sensitive), so it'll simply give an error. :)
I should also say that, although you usually won't need it, the subtraction order goes backwards, like so:
 76-14-53 = 76-(14-53) -> osmium-(silicon-iodine) = "os"-("si"-"i") = "os"-"s" = "o"
Yes, I just used 8 characters to make an "o", when I could just use Oxygen (8), which is one character. You really can obfuscate code with this technique.
There's nothing stopping you from doing
 32-34-38-59-91-18-103-3-53 = ... = g
===Multiplication===
Multiplication duplicates the elements in a weird way, so I'd recommend not using this unless you absolutely need it.
 2*8 -> 2oxygens+8heliums = "o"+"o"+"he"+"he"+"he"+"he"+"he"+"he"+"he"+"he" = oohehehehehehehehe
The algorithm is laughing at you
If you really wanna multiply elements as you'd expect, I'd recommend using explicit numbers, which you can find in the next section.
===Division===
Division only takes one input, and that's the element to be divided. It technically reverses the element. Here's an example:
 /22 -> /titanium = /"ti" = "it"
Might be helpful, might not, you decide.
Okay yeah it is helpful for pretty much every conditional code you wanna do, as the primary keyword for this (goto) uses /118 (/og: go). Its better than using 118-8+8.
==Examples==
Here are some examples of code I made using HeLiiLii, I'll decode it and explain how it works too :)
The final translated code is very similar to pseudocode, if you need any help, DM me on discord (Magnogen#2500) and I'll explain it and make updates to this page.
