MankeDoMath
by TVTvirus
A server-side calculator command, MankeDoMath, lets players solve sums, shulker and stack counts, and time estimates inside the game chat.
What it does
MankeDoMath registers a command that the server runs, so players join without installing anything. The client autocompletes it through the vanilla command tree. Expressions can carry units, so an input such as 5sb 2h gives an output per hour, and longer spellings like stacks, shulkerboxes, items, minutes and chunks are accepted alongside the short forms. Shorthand like sh still works, and a bare x between numbers is read as multiplication.
The mod depends on Fabric API and is published for Fabric only, across 17 release versions 1.21 – 26.3, with 1.2.1+26.3 as the latest file for 26.3. Only the server needs the jar, and the code is open source under the MIT License, with public links to the source and the issue tracker. The math logic is plain Java, and its checks run automatically on every push. A build is produced by running the JDK 21 build, with the jar placed in build/libs/.
Key features
Units through arithmetic
Units carry through calculations, so a rate with a time unit prints its result per hour or per other period.
Shulker and stack counts
Quantities expressed in shulker boxes, stacks, items, minutes and chunks can be combined and converted in one expression.
Built-in functions
Common functions such as roots, minimum and maximum, absolute value, rounding and logarithms are available in expressions.
Configurable limits
Four limits on expression length, nesting depth, operation count and exponent size are checked before a calculation runs, and a cap stops oversized powers with a message.
Optional humorous errors
Funny error messages can be turned off with a config setting, leaving plain Brigadier error output.

How it compares
Damage Calculator is client-side only, runs on 1.21.11 and is not open source. Calculator In Chat is client-side only, runs on 1.21.8 and uses a custom license. In Game Calculator is client required with server optional, covers 1.21.6 – 26.3 and is released under CC0 1.0 Universal, so it is not open source by the MIT standard used here. Star Calculator and Enchant Calculator are both client-side only and open source under the MIT License, covering 26.2 – 26.3 and 1.21 – 26.3.

What the author says
A calculator inside Minecraft that knows what a shulker is. Quick sums without leaving the game or reaching for your phone, aimed at what a technical player actually works out: farm rates, how many shulkers a pile of items is, how long something takes to fill.
