Calculators
Scientific calculator
It reads a whole expression rather than one keypress at a time, so you can see what you are about to calculate: the result updates as you type, and = commits it. Trig in degrees or radians, memory, and a history you can click back into. The arithmetic all happens in the page — nothing you type is sent anywhere.
This is the home of the section: the panel on the left comes back here from every other page.

What it understands
Operators
- + − × ÷ the four basics
- ^ power, right associative: 2^3^2 = 512
- ! factorial, whole numbers 0 to 170
- % percent — divides by 100, so 50% is 0.5
- ( ) grouping; 2π and 3(4+5) multiply implicitly
Functions
- sin cos tan asin acos atan
- sinh cosh tanh
- ln log log2 exp
- sqrt cbrt abs sign
- floor ceil round trunc
- mod(a, b) root(x, n) pow(a, b)
- log(x, base) any base you like
Names and memory
- pi tau e phi
- ans the previous result
- M calculator memory, via MC MR M+ M−
- Degrees or radians, from the DEG/RAD chip
Keyboard
- 0–9 . + − * / ^ ( ) ! %
- Enter or = commit the calculation
- Backspace delete · Esc clear
- Letters type names: sqrt(2), mod(10,3), pi
