Help & Guide

Everything you need to get the most out of EqualNote, the inline calculator notepad.

Last updated: August 12, 2026

Quick start

Just start typing. Any line that ends with = is treated as a calculation, and the result appears right after it — inline, in your text.

1+2= → 1+2=3
(3+5)*2= → (3+5)*2=16
Mix text and math freely: groceries 3*5= and fruit 2+8=
Each line is independent, so you can keep a running list and edit any line — results update live.

Supported operators

Addition +, subtraction −
Multiplication × (also *), division ÷ (also /)
Power ^, parentheses ( )
End a line with = to compute it.

Variables

Define a value once with a name, then reuse that name anywhere below. Variables keep multi-step calculations and "what-if" scenarios clean — change the input once and every dependent result updates.

Define: write name = value (or name=value, without spaces) on its own line. A name may contain letters, digits, and _, and can be non-Latin too — for example price = 100 or 税率 = 0.08.
Use it: reference the name in any later expression. price * 1.2 = uses the value of price.
Chain: a variable defined later can reference one defined earlier. Define tax = price * 0.08, then total = price + tax = shows the combined result.
Many on one line: you can pack several on a single line — a = 1 b = 2 a + b = and the final = shows 3.
Result pills: a plain constant assignment like rate = 0.05 shows no result pill (it would just repeat the value). An assignment that does a calculation, like total = price + tax, shows its result pill.
Redefinition: if you assign the same name twice, every occurrence is highlighted and the last one wins. Hover any of them to see "redefined: later overrides earlier."

Errors to watch: referencing a name before you define it, or creating a circular chain (e.g. a = b + 1 together with b = a + 1), leaves the result as ∞ until the references resolve.

The operator bar

A vertical bar sits on the right edge of the screen. Its buttons insert operators at your cursor — handy on touch devices.

Move it: long-press the blue handle at the top, then drag. Its position is remembered.
Collapse / expand: tap the blue handle to hide or show the operator buttons. The collapsed state is remembered too.
Only the handle is draggable; the operator buttons are pure taps, so you never move the bar by accident.

Copy text: copies your notes with results as plain text (e.g. 1+2=3).
Share link: encodes your notes into a URL, so anyone who opens it sees the same content and results.

Themes

Use the menu at the top-right to switch between Light, Dark, and System (follows your device). Your choice is saved.

Languages

Tap the globe button to choose from 16 languages. The interface — and your preference — are remembered.

Keyboard tips

Just type as you would in any text editor; results appear as you go. The caret moves naturally with arrow keys and Tab. Inserting operators from the operator bar is just as smooth as typing them.

Troubleshooting

No result appears? Make sure the line ends with =.
