Your first worksheet
A worksheet is a page. Click anywhere on it and type: what you type becomes math at that spot.
Define a value
Section titled “Define a value”Click on the page and type:
L:6mThe colon becomes the definition sign, so the page shows L := 6 m. Press Enter to finish.
Below it, define a load:
q:12kN/mWork something out
Section titled “Work something out”Below both, type:
M:q*L^2/8=Beermat shows M := q·L²/8 = 54 kN·m: a definition, and its result after the =. The result has units, worked out from the units you typed, with the prefix that keeps the number readable.
Show it in other units
Section titled “Show it in other units”Type the unit you want right after the =. Below, type:
M=N*mThe page shows M = 54000 N·m. A unit that doesn’t fit (kN alone, for a moment) shows an error instead of a wrong number.
Change a value
Section titled “Change a value”Click on 6 m and make it 8 m. Every result below it changes at once: the page is worked out from top to bottom, then left to right.
Save it
Section titled “Save it”File → Save writes a .bbm file. It is plain text (Markdown), so you can read it in any editor, keep it in Git, or hand it to an AI assistant.
