Math
Design Intent: Write the sum the way you would say it. Numbers in a sentence are still numbers.
Calculations
- Type
mathon the first line. Any line that ends in=is calculated and the answer is written after it; change the line and the answer updates. - Words between the numbers are ignored, so
$4.25 for lychee + $21 for moon cakes =works. ansstands for the previous answer above the line. Rename it in Settings › Editor › Previous answer word.- Lines starting with
//are comments and are not calculated. Answers are protected: you cannot type over them. - The Math keyboard puts operators,
ans, units and variables under your thumb — see Special keyboards. The Math quickbar switches in automatically on a math note.
Variables
- A line like
guests: 5defines a variable. Use it anywhere below:guests * 34 =. Change the definition and every answer that depends on it updates. - A variable's value can itself be a calculation:
daily: hourly rate * 8 =. - The Math keyboard's Vars sheet lists the note's variables and can add a new one.
